1.0 Introduction
This report presents results from an analysis of light-duty gasoline-powered vehicle On-
board Diagnostic (OBD) evaporative emissions control system (evap) diagnostic trouble codes
(DTCs) using inspection and maintenance (I/M) program data from four states. The purpose of
this analysis was to better understand evap monitor readiness trends, to quantify evap DTC rates
for light-duty vehicles subjected to an I/M program, and to better understand the prevalence and
interrelationships of evap DTCs in an I/M fleet. Evaporative monitor readiness results were
assessed for initial tests and retests, and for those vehicles that did have an evaporative monitor
status of "ready", evaporative DTCs were evaluated by vehicle model year (1996 and newer) and
calendar year (calendar years 2003-2011). Evaporative monitor readiness was also evaluated to
better understand readiness trends, to determine if evaporative monitor readiness status might be
masking evaporative trouble codes, and to determine how many vehicles never have a "ready"
evaporative monitor over multiple inspection cycles. In this context, an inspection cycle
generally consists of one or multiple tests performed within a four-month window, usually until a
pass is achieved or a waiver is issued. A large percentage of the inspection cycles in the I/M
programs for these states consist of a single passing inspection for a vehicle within that four
month period (additional details regarding "initial" tests and "inspection cycles" are provided in
Section 2.1, "Defining Initial Tests"). Trends in readiness and DTC rates were evaluated and
compared by calendar year, vehicle model year, inspection cycle and vehicle age across the four
states of analysis. Individual evaporative DTCs were also tracked for specific vehicles over
multiple inspection cycles in an effort to better understand the efficacy of evaporative system
repairs, and evaporative DTC combinations were evaluated to better understand the interactions
and interdependence of evaporative system DTCs.
In this report, the results of analysis of data from four states (identified as "State A"
through "State D" for anonymity) are presented. The data was split into calendar year for each
state, and only model years 1996 and newer were included in this analysis. Pre-1996 model year
vehicles weren't included in the analysis since OBDII compliance was not federally mandated
until model year 1996. Although OBD monitoring of evap control systems was present
beginning with model year 1996 vehicles, enhanced OBD evap monitoring of federally-certified
Tier 1 vehicles began in model year 1996 but was not fully phased-in until model year 1999
vehicles (enhanced evap phase-in of California-certified NLEV vehicles began in model year
1995 with full phase-in by model year 1998 vehicles). Because enhanced OBD evap monitoring
of federal vehicles was not fully phased in until model year 1999 vehicles, some report results,
such as readiness trends presented in Section 2.4 and DTC trends presented in Section 3.2, only
include model year 2000 and newer (enhanced evap) vehicles. Also, when reviewing results, it
1
-------
should be noted that federal phase-in of Tier 2 evap requirements began in model year 2004 with
full compliance by model year 2007, while phase-in for CARB LEVII evap requirements began
in model year 2004 with complete phase-in by MY2006.
The standards to which new vehicles are certified may have an influence on DTC rates
presented in this report. Phasing in from model years 2000-2003, California-certified vehicles
(vehicles either sold in California or in other states that have adopted California standards) were
equipped with 0.020" leak detection monitoring (in lieu of 0.040" federal leak detection
requirements). This may account for some difference in detected evap failures, and hence
reported evap DTC rates, if some vehicles included in this analysis conformed to tighter
monitoring standards and could theoretically identify more evap system failures.
The date states acquired the ability to test vehicles with CAN (controller area network)
communication could slightly alter the fleet receiving OBD inspections (and hence evap rates),
although with the federally-mandated 2004-2008 CAN rollout and the new model year
exemption, this will have a very minimal impact on fleet profile and overall study results over
the period of evaluation.
The data from these states spans the calendar years of 2004 through 2012, depending on
data available from each state at the time of analysis. Table 1 shows the calendar years of data
analyzed for each state as well as the I/M program cycle frequency (annual or biennial) and
model year exemption period for the I/M program during the calendar years of data analyzed for
each state. The last column highlights each state's readiness criteria (how many "not ready"
monitors are allowed for each state's OBD test), although as stated previously each state's ready
criteria was not used in this evaluation. When comparing results among states, it is noteworthy
that differences in average ambient temperature ranges, altitude or vehicle fleet longevity
(vehicle age distribution) among the states could impact each state's evap readiness rates and
DTC results presented in this report.

N/A, OBD not enforced
In order to minimize the differences of State I/M programs, the OBD readiness
determination and OBD pass / fail determination from each state's program were excluded from
analysis. The results in this report are based on the OBD evap monitor readiness status (without
regard to the state's I/M readiness determination) and the presence (or lack of) evap-related
DTCs (without regard to MIL command status). In Section 3 (DTC Analysis), all vehicles with a
"not ready" evap monitor are excluded, and the calendar year / model year percentages are based
only on those vehicles with a "ready" evap monitor, unless otherwise indicated. In addition, the
DTC analysis results in this report are based on all I/M records with evap DTCs, regardless of
MIL command or pass/fail status of the test. Therefore, the evap DTC rates presented in this
report may include non-active (historical) codes and be higher than would be seen using only
I/M fails (evap DTCs with MIL commanded on). These history codes don't represent a current
malfunction but a problem that occurred sometime in the vehicle's recent past. Information
regarding the impact of the use of these codes with no MIL illumination is provided in Section
3.0.
The OBD ready criteria for State D indicates that the OBD program is not enforced. This
means that the OBD test result is not a criteria for passing or failing an inspection. The pass / fail
determination for that state is based on results of an IM240 tailpipe test and a gas cap
functionality test. A vehicle that fails the IM240 or gas cap test fails the overall test and must
pass a re-inspection to receive an overall pass. A vehicle with stored OBD codes and an
illuminated malfunction indicator light (MIL) will not fail the test unless the vehicle also fails the
IM240 test or the gas cap functionality test.
A summary of the analysis objectives and results of analysis is provided in the following
sections.
-------
2.0 Summary of Analysis Results for Evap Monitor Readiness
In order to understand and quantify the evap DTC rates, vehicles with an evap monitor
ready at the time of the I/M test were first identified. Therefore, the first part of the analysis
involved quantifying how many vehicles had a "ready" evap monitor at the time of the initial or
re- inspection for one inspection cycle.
The objectives for the analysis in this section were to quantify the percent of vehicle
inspections with evap monitors "ready and "not ready" at the time of inspection, evaluate the rate
of readiness as vehicles age, and compare the results among the states to determine if the
increase of "not ready" vehicles was similar for each state.
2.1 Defining Initial Tests
The purpose of the analysis was to quantify the percent of inspection cycles with an evap
monitor status of "not ready" for each inspection in the cycle, so it was important to define each
vehicle's inspection cycle by finding the initial test in each cycle. The analysis was performed
using multiple calendar years of I/M data for each state. Before finding the initial tests in the
dataset for each state, the datasets were filtered to remove any suspect I/M records and any data
points not to be considered in the analysis. A general summary of the data QC and filtering
performed on the states' data is contained in Appendix A.
The procedure for defining an initial test varied from state to state, depending on how
each state organizes its I/M data and what records and data are stored in each database. For state
A, the test record for any vehicle that completes and passes a final test in an I/M cycle contains a
sticker number (this indicates the vehicle completed all I/M program requirements for that year).
This sticker number is used to identify final tests in each I/M cycle (and hence the initial test for
the next cycle).
In other states, a variety of methods were used to determine initial tests and inspection
cycles. In states B and D, an initial I/M test was defined by finding an I/M test which followed a
record with an overall result of "Pass". For State B, this method was used in conjunction with the
file that lists all the waivers in State B, because for a small portion of the vehicles, a final test can
still have a result of "Fail" when a waiver was issued.
In state C, the sticker number could typically be used to determine the initial test;
however, in about 5% of the records the sticker number did not adequately define the initial tests.
For these tests, the time between two tests was calculated. If the time elapsed between any two
-------
tests was more than 180 days (even if no valid sticker number was issued), the test that was over
180 days later was defined as an initial test.
2.2 Percent of Initial Inspections with Ready Evap Monitors
Table 2 summarizes the evap monitor readiness status for all initial inspections from each
state. Note that these percentages represent the percent of inspections for vehicles in the I/M fleet
that are not ready at the time of their initial inspection. In some cases, this may be vastly
different from the percent of vehicles in the registered fleet that would have evap monitors not
ready, because each state has an exemption period for new vehicles. Depending on the number of
years exempted from I/M testing, the I/M fleet will be significantly older and could therefore
have a higher incidence of evap monitor "not-readiness" than the registered fleet (based on evap
monitor readiness vs. vehicle age trends shown in Section 2.4).
From Table 2, it can be seen that the percent of initial inspections for vehicles in the I/M
fleet with an evap monitor "not ready" ranged from approximately 9% to 12% (evap monitor
readiness ranged from approximately 88% to 91%). The highest incidence of evap monitor not
readiness at initial inspection was in State A, where almost 12% of the vehicles receiving initial
tests had evap monitors that were not ready. Table 1 shows that State A also has a 6 model year
exemption for new vehicles for I/M testing, which could indicate that State A would have the
oldest I/M fleet. The age distributions of the vehicles tested in each calendar year were calculated
to determined the relative age of each of the I/M fleets of States A, B, C, and D, and it was
determined that the age of the I/M fleet is older for State A than for the other states. For example,
in calendar year 2008, 88% of the inspections in State A were for vehicles that were 6 years old
or older. In comparison, in States B, C, and D for calendar year 2008, only 62% - 70% of the
inspections were for vehicles 6 years old and older.

Table 2 shows that across different I/M programs with varying calendar years of data
present, the results all show that approximately 90% of the initial inspections have evap monitors
-------
ready. The results indicate that about 10% of the initial inspections in any given I/M program are
going to have an evap monitor that is not ready. The similarity in this percentage for all of the
states suggests that this number could approximate a national percentage of initial inspections
with "not ready" evap monitors for vehicles in an I/M fleet.
2.3 Percent of Test Cycles with Ready Evap Monitors
For this analysis, the readiness of all tests within inspection cycles (not just the initial
test) was analyzed to determine the number of inspection cycles with a "not ready" evap monitor.
In many cases, there was only one test for the vehicle in the I/M cycle, but in some cycles, the
vehicle received multiple inspections. In the previous section, it was found that roughly 9% to
12% of the initial inspections had an evap monitor status of "not ready". Table 3 shows that these
percentages decrease to 7% to 11% for all inspections in an I/M cycle. This trend of an increase
in evap monitor readiness is likely due to the fact that the evap monitor has multiple chances to
achieve readiness in inspection cycles (as opposed to one chance in a single inspection). These
multiple chances are the likely cause of the increase in evap monitor readiness, despite the
possibility of OBD resets resulting from vehicle repairs and battery disconnects during the
inspection cycle. This increase in readiness indicates that "not ready" evap monitors occasionally
achieved readiness for retests in inspection cycles with multiple tests. Similar to the initial test
results from the previous section, the percentage range of "not ready" evap monitors is very
similar among all the states that were analyzed and could approximate a national percentage of
vehicles in I/M programs with "not ready" evap monitors.

Note: These results are for model years 1996 and newer
When comparing these results with previous analysis of non-evap OBD monitors, the
percentage of "not ready" evap monitors was much higher than for other OBD monitors. For
example, when looking at all the OBD monitors' readiness for one of these states, the non-evap
OBD monitors had an overall "not ready" percentage in the 1% - 2% range instead of the 7%-
11% range seen for the evap monitor. As the OBD evap monitor is typically subject to more
-------
rigorous enabling criteria (specific vehicle operation and soak requirements) than other monitors
in order to achieve readiness, this monitor is generally one of the last monitors to achieve
readiness, and will likely have a higher fleet-wide "not ready" rate than other monitors at any
point in time (such as during an I/M inspection). Due to the longer "not ready" period of the
OBD evap monitor, it is possible that attempts to mask MIL illumination in order to pass an I/M
test (through a battery disconnect or code clearing) could contribute somewhat to the OBD evap
monitor readiness rates being lower than those of the other monitors in the I/M data evaluated for
this study.
2.4 Trends of Evap Monitor Readiness by Vehicle Age
The next analysis involved determining the trend of the increase of the percent of
inspections with "not ready" evap monitors by age for each state and to compare the trends
across the states. To do this the data was separated by calendar year and vehicle model year and
tabulated the evap monitor readiness status of all the inspection cycles for each of the states.
Specifically, the calculations involved finding the percentages of inspection cycles in which the
vehicle's evap monitor was "ready" for at least one test during the cycle, and results for each
state were graphed to illustrate the trends of evap monitor readiness for vehicles as they age.
These results are shown in Figures 1 through 4.

On the figures, only model years 2000 and newer are shown. This is because although
OBD evap systems were present in some 1996 vehicles, full phase-in of enhanced evap OBD did
not occur until 1999. In order to develop trend lines for the evap monitor readiness percentage by
age, using only 2000 and newer model years (a full year after phase-in was complete) ensures
that the data used would be most representative of the trends for enhanced evap vehicles. In each
graph, the different colored lines with points represent the actual data from each model year and
age for the state. The solid black line with no points shows a trend line1 for all model years
which predicts the percentage of evap monitor readiness at a given vehicle age. The analysis was
conducted to calculate the percentage of inspections with "ready" evap monitors for all vehicles
in a given age (from 2 to 10 years old in most states). The vehicles at any given age can have a
range of odometer values, so they may not all be in the same condition in terms of wear-and-tear
and mileage.
The reference lines on the graphs which cross at 89% and 96% to help in comparing the
figures for each of the states. When comparing the figures, it can be seen that States B and C
have readiness percentages that are close to one another, about 98% evap monitor readiness for 2
year old vehicles, and about 89% evap monitor readiness for 8 year old vehicles. In comparison,
States A and D have lower readiness rates (90% to 94%) for the 2 year old vehicles than States B
andC.
The graph of State A differs from those of the other states. First, the range of the
percentage of inspection cycles with "ready" evap monitors for all model years at a given age is
larger than for the other states, especially for the newest vehicles. For example, a 2 year old
vehicle in State A has a range of 87% - 99% of the inspections with an evap monitor ready, while
that range is only 91% - 95% for state D. State A has a 6 model year exemption (with test-on-
resale after a vehicles is 4 years old), so the number of 2 year old vehicles in that dataset is small
compared to the vehicles in the other model years. These vehicles are probably not representative
of the 2 year old vehicles in the I/M fleet, as they are most likely vehicles that have moved into
the state from another area or are coming in for an inspection for some other reason even though
it is not required. This is one possible explanation for why the percentage of 2 year old vehicles
with evap monitors "not ready" in State A is larger than for 2 year old vehicles in other states.
Also, State A has a biennial inspection frequency. Vehicles start receiving tests when they are 6
years old and then are only tested every other year after that. The "zig-zag" on the curves follows
a biennial trend (this trend is also evident but not as pronounced for states C and D, the other
biennial programs). The inspection totals by calendar year and age (shown in the tables in
1 Trend lines were developed using linear regression techniques.
12
-------
Appendix B) show that the total number of inspections is lower for these "off I/M years, and the
overall average readiness is also lower for these "off I/M years.
The other state that has percentages that do not fall on the reference lines for the 2 and 8
year old vehicles is State D, which does not enforce the OBD program and therefore OBD
monitor readiness is not a requirement for the I/M test.
The results in the graphs for each state show that vehicles were more likely to have an
evap monitor status of "not ready" as the vehicle aged. The percentages and rates of increase of
evap monitor not readiness differed for some of the states. The vehicles in state D were more
likely than the other states to have an evap monitor status of "not ready", even when they were
only 2 years old, and the slope of the increase of evap monitors being not ready as vehicles aged
was not as steep as for States B and C.
Figure 5 shows the tendency of readiness decreasing as a function of vehicle age more
clearly. Trend lines of the "predicted" percentage of vehicles with an evap monitor ready versus
age are shown, and it can be seen that the slope of the lines for States B and C are steeper than
for States A and D. States A and D have nearly identical rates of decrease in readiness by vehicle
age, although State A is approximately 5% lower than State D. Individual tables listing results
for each state are provided in Appendix B.

2.5 Trends of Evap Monitor Readiness by Age with Out-of-Cycle Tests
Removed
The data presented in Figure 5 above shows the results of the trend line predicting the
percent of inspections with evap monitors ready versus vehicle age. The results in Figure 5 show
that the slopes of the lines (the decrease in the rate of readiness as vehicles age) for States A and
D are different than the slopes for States B and C. For State A especially, this could be due to the
fact that there is a 6 model year exemption period for I/M testing, so the vehicles less than 6
years old that receive an I/M test may be resale vehicles and may not be in the same condition as
similarly-aged vehicles in the rest of the fleet. Also, most of these states have a biennial I/M
program, so the number of inspections in these out-of-cycle years is lower than for the on-I/M
cycle years, and the readiness rates seen in these out-of-cycle years is lower on average than the
in-cycle years.
Since out-of-cycle inspections may be due in part to vehicles moving into the state and/or
resale vehicles, results from these out-of-cycle inspections might differ from the in-cycle I/M
program results, so for comparison to Figure 5 the dataset was modified for each of the states to
only include inspections of vehicles that would typically be subject to the I/M program at the
time of their inspection. This involved removing inspections in which the vehicle was too new
for the I/M inspection and also removing inspections during an "off year in the biennial I/M
programs. Once the datasets for each state were modified in this way, the trend lines2 of vehicle
age versus the percentage of vehicle inspections with a "ready" evap monitors ready for at least
one test during the cycle were recalculated. Figures 6 and 7 show the results from these trend
lines calculated with the modified datasets. It should be noted that this was done only to evaluate
the effect of "out-of-cycle" I/M inspections on the evap monitor readiness rate in each of the I/M
programs. Removing these "out-of-cycle" tests appears to increase the evap monitor readiness
rate from the overall rates seen in each I/M program (in-cycle and out-of-cycle tests inclusive).
States A and C are both enforced biennial programs, and therefore there are more enforced "out-
of-cycle" tests in States A and C than in States B and D (State B is an enforced annual program
and State D is biennial but unenforced for OBD). Additional influences may also arise due to
vehicles moving into the various states from non-I/M areas and being subjected to an I/M
program for the first time. Investigation into the causes of differences in evap readiness rates
between "in-cycle" and "out-of-cycle" tests was beyond the scope of this work assignment and
was not performed.

Figure 6 shows that once the out-of-cycle inspections were removed, results from all four
states have very similar percentages of vehicle readiness by age. This graph shows that as a
vehicle ages, it will be more likely to have an evap monitor "not ready" during an I/M cycle, and
that the increase in its likeliness of having an evap monitor "not ready" is approximately 1% per
year as the vehicle ages (for vehicles in their I/M inspection cycle).
Figure 7 shows combined linear trend lines of the unmodified and modified data sets.
This graph is a combination of Figures 5 and 6.
2.6 Multiple Inspection Cycles with Evap Monitors "Not Ready"
The purpose of this next analysis was to identify patterns of vehicles having "not ready"
evap monitors for all inspections over multiple consecutive inspection cycles. The subset of
vehicles for which the evap monitor was "not ready" for all tests in an inspection cycle was
evaluated, and the evap monitor status for those vehicles was tracked across inspection cycles on
subsequent calendar years. Even though previous results indicated that up to 15% of inspections
for older vehicles could have a "not ready" evap monitor, the results of this analysis show that
those are not the same vehicles each time. The results from all states show that most vehicles
(over 97%) have an evap monitor status of "not ready" only one or two times in their entire I/M
history. For the vehicles that were in the data for at least 2 inspection cycles, only about 0.5% of
them have an evap monitor status of "not ready" each time they come in for an inspection.
3.0 Summary of Analysis Results for Evap DTCs Set
An analysis of the number of evap DTCs set during any test in the I/M cycle was
performed for all vehicles that had a ready evap monitor for at least one inspection during an I/M
cycle in each calendar year. Several OBD PO and PI DTCs that pertain to the evaporative
emissions control system were considered3. Less than 0.1% of the DTCs present were P2 or P3
codes. The generic (PO) SAE J2012 evap DTCs of interest for this study are listed in Table 4,
along with the evap-related PI (manufacturer-specific) fault codes. SAE J2012 definitions are
provided for all generic PO fault codes, but PI codes were defined based on Internet research (as
shown in Table 4). In general, the evap-related PI (manufacturer-specific) fault codes included
in this analysis correspond to the generic PO fault code categories.
As previously stated, all evap DTCs were considered in this analysis, regardless of MIL
command status. Consequently, the evap DTC rates presented in this report may include non-
3 P2 and P3 codes were not considered in this analysis due to the small numbers of those codes present in the states'
data.

active (historical) codes and be higher than would be seen using only I/M fails (evap DTCs with
MIL commanded on). These history codes don't represent a current malfunction but a problem
that occurred sometime in the vehicle's past but that is not yet cleared from the vehicle's OBD
system. It was not possible to determine how long it had been since the MIL had been
extinguished for these history codes. The number of these history codes varied among states. For
states A and D, approximately 30% to 50% of all evap DTCs are present without a MIL
commanded on, while for States B and C, the DTCs without a MIL commanded on comprised
less than 15% of all evap DTCs. These DTCs with no MIL illumination were included in the
analysis to provide as much information as possible regarding potential evap problems in the
vehicle fleet, but it's possible some of the DTCs may be indicative of a problem that existed but
is now corrected and has not been cleared from the vehicle computer's history yet. Therefore, the
overall DTC rates presented in this report are not intended to represent I/M program evap fail
rates, since vehicles with evap codes but no MIL illumination would not have failed the OBD
I/M inspection based solely on the presence of evap codes.
The following subsections provide summary analysis results, and additional details are
provided in the report appendices.

3.1 Percent of Evap Monitor Ready Inspections with Stored Evap DTCs
For all vehicles with a "ready" evap monitor the number of vehicle test records
containing evap-related DTCs for each inspection cycle was tabulated by calendar year and
model year. Using these results, the percentage of all inspection cycles containing an evap DTC
was calculated.
The results, shown in Table 5, indicate that between 0.7% and 2.5% of the inspection
cycles for vehicles with a "ready" evap monitor have a stored evap DTC. Approximately 10% of
the inspections do not have an evap monitor ready, and for these, the percent of inspections with
evap DTCs was not calculated, as these vehicles with "not ready" evap monitors could provide
an artificially low (unrepresentative) evap DTC rate since the OBD system hasn't completed
evap system testing for these vehicles.
The State A percentage of 1.6% may be slightly higher than the rates for States B and C
because of the six model year exemption period in State A, (which results in an older I/M fleet
than the other states). State D's 2.5% DTC rate may be due to the fact that OBD results are not
enforced in State D. In State D, OBD tests are performed in an advisory capacity, but a vehicle
can pass the I/M test with the MIL commanded on. The main pass/fail determination is based on
the IM240 and gas cap functionality test results, unlike the other states (States A, B, and C)
where the OBD test is the enforced for 1996 and newer vehicles, so an OBD failure results in an
overall test failure.

3.2 Trends of Evap DTCs Set by Age
The next analysis involved determining the trend of the increase of the percent of evap
monitor "ready" inspections with evap DTCs by age for each state and to compare the trends
across the states. The test records with a "ready" evap monitor by calendar year and model year
were binned, and the percent of inspections with stored evap DTCs by state were tabulated.
Results were graphed for each state to illustrate changes in the trends of evap DTCs as vehicles
age. The results are shown in Figures 8 through 11.

Only model years 2000 and newer are shown in the figures. As stated in a previous
section, this is because full phase-in of the enhanced evap OBD system did not happen until
1999, and using only 2000 and newer model years (a full year after phase-in was complete)
ensures that the data used would be most representative of the trends for enhanced evap vehicles.
In each graph, the different colored lines with points represent data for each model year and
vehicle age for each state. The solid black line with no points shows a trend line for model year
2000 and newer vehicles, predicting the percent of vehicle tests that would have a stored evap
DTC at a given age. The trend lines4 for each state represent the percentage of stored evap DTCs
at each age for each calendar year combined. The analysis was conducted to calculate the
percentage of evap monitor "ready" inspections with stored evap DTCs for all vehicles in a given
age (from 2 to 10 years old in most states). The vehicles at any given age can have a range of
odometer values, so they may not all be in the same condition in terms of wear-and-tear and
mileage.
Although linear trends were found to be most suitable for the ranges of interest of the
combined data, the by-model-year graphs do show a slight curvature, especially as the vehicles
age. For State A, the rate of vehicles with evap DTCs seems to increase after the vehicle age of 5
years, possibly due to State A's model year exemption of 6 years. Then, all states appear to show
a general trend of a slight drop in the rate of evap DTCs after 7 years of age. This could be due to
aging vehicles retiring out of the fleet or other factors, and additional analysis could be
performed to fit the data more closely for the newer and older age vehicles. The trend lines were
simply provided to show the general trends for vehicles under 10 years of age.
The graphs for each state have reference lines to facilitate comparison among the states.
The horizontal reference lines cross at 0.5% and at 1.5% of the vehicle inspections with "ready"
evap monitors and with evap DTCs set. States B and C have percentages of evap DTCs set that
are below these two horizontal reference lines at ages 2 years old and 8 years old. The other 2
states, States A and D, have DTC percentages that are at or above the 0.5% and 1.5% reference
lines.
Again, State A has a 6-year exemption for new vehicles and only performs test-on-resale
after a vehicles is 4 years old, so the 2 to 5 year old vehicles in that dataset may not be
representative of the fleet. State D does not enforce the OBD program and therefore, having an
OBD evap DTC set with a MIL illuminated is not a basis for failing an inspection. Therefore, it
is expected the rate of evap DTCs will be higher since motorists are not required to make repairs

-------
based solely on MIL illumination. The differences in these programs may explain the higher
percentage of evap DTCs set than in the other 2 states.
The graphs show that vehicles were more likely to have stored evap DTCs as they aged.
The rate of increase of evap DTCs as vehicles aged was not as steep as for States B and C as it
was for states A and D. Figure 12 shows the trend lines for all four states combined. On that
graph, it can be seen that the slope of the lines for States A and D are steeper than for states B
and C, with the slope for state D being the steepest. This shows lower rates of evap DTCs in
states with enforced OBD programs.
The individual tables in Appendix C show the results for each state in more detail.

3.3 Trends of Evap DTCs Set by Age with Out-of-Cycle Tests Removed
The data presented in Figure 12 shows the results of the percent of inspections with evap
DTCs set versus vehicle age.
This dataset was then modified for each of the states to only include inspections of
vehicles that would be subject to the I/M program at the time of their inspection. This was done
to allow a comparison between the complete I/M dataset and a modified dataset including only
"in-cycle" tests. To create the modified datasets, all inspections in which the vehicle was too new
for the I/M inspection and inspections performed in the "off year (for biennial I/M programs)
were removed. Once the datasets for each state were modified in this way, the trend lines for the
percent of vehicle inspections with "ready" evap monitors and stored evap DTCs versus vehicle
age were calculated. These revised trend lines are shown in Figures 13 and 14. It should be noted
that this was done only to evaluate the effect of "out-of-cycle" I/M inspections on evap DTC
rates in each of the I/M programs, as removing these "out-of-cycle" tests may bias the evap DTC
rates upward from the overall rates seen in each I/M program (in-cycle and out-of-cycle tests
inclusive).
Figure 13 shows that three of the states have very similar rates of increase of evap DTCs
as the vehicles get older. For these three states, the figure shows that older vehicles are more
likely to have stored evap DTCs, and the likelihood that a vehicle will have a stored evap DTC
during the I/M cycles increases by approximately 0.15% per year.
The slope of the fourth state, State D, is over 3 times higher than the slope of the other
three states, which as stated previously is likely due to the fact that OBD is not enforced in State
D. It is possible that the slope of the line for State D is indicative of the minimum rate of increase
of evap DTCs in a non-I/M area. The rate of increase in a non-I/M area could be even higher
than the slope for State D, because State D does perform the OBD test on an advisory basis, does
have an evap repair consumer assistance program, and does have an I/M program that includes
an enforced gas cap test.
Figure 14 shows combined trend lines of the unmodified and modified data sets. This
graph is a combination of Figures 12 and 13. It is interesting to note that the State A and C
modified and unmodified datasets have very different slopes, while the slopes for the modified
and unmodified datasets for States B and D are similar. This could be due to the fact that States
A and C are both enforced biennial programs, and therefore there are more enforced "out-of-
cycle" tests in States A and C than in States B and D (State B is an enforced annual program and
State D is biennial but unenforced for OBD). Additional influences may also arise due to
29
-------
previously-untested vehicles moving into the various states and being subjected to an I/M
program for the first time. Investigation regarding the root causes of differences in evap DTC
rates between "in-cycle" and "out-of-cycle" tests was beyond the scope of this work assignment
and was not performed.

3.4 Evap DTC Rates for States Combined
The results from section 3.3 showed that when out-of-cycle tests are removed from the
data, three of the states have very similar rates of increase of evap DTCs as the vehicles get
older. For all states, the results show that older vehicles are more likely to have stored evap
DTCs, and the likelihood that a vehicle will have a stored evap DTC during an I/M cycle
increases by over approximately 0.15% per year.
In this section, the number of evap DTCs set by calendar year and model year for those
three states (States A, B, and C) were combined to calculate one trend line5 of the percent of
evap DTCs set by vehicle age. The trend line for States A, B, and C combined were plotted
versus the trend line for State D alone so that the results of States A, B, and C combined (states
with an enforced OBD program) could be compared with State D (without an enforced OBD
program). In order to avoid biasing results based on how an I/M program is administered (i.e., 6
model year new vehicle exemption vs. 3 model year new vehicle exemption), all three programs
were weighted equally (the slope of the composite trend line was not weighted based on the total
number of tests analyzed for each program). Also, as stated previously, State D could represent
a conservative (low) estimate of the evap DTC percentage in a non-I/M area because State D's
OBD test result is not enforced. However, it is expected that the evap DTC rate in a non-I/M area
would be higher, because although OBD is not enforced in State D, it does have an enforced I/M
program with a fuel cap test, and OBD tests are conducted on an advisory basis.
Figure 15 shows the results. The points on the figure show the individual data points from
States A, B, and C combined (in black) and from State D (in red). Each data point on the graph
represents one calendar year and model year combination of the percent of evap DTCs set for
one state. The results in Figure 15 show the differences between the percentage of evap DTCs
for vehicles at different ages when there is an OBD I/M program which includes evap and when
there is not an enforced OBD I/M program but there is a fuel cap inspection.
5 Trend lines were developed using linear regression techniques.

The data points on the graph show the range of values of the percentage of evap DTCs by
age for two sets (states A, B, and C combined and state D). The data points on the graph show
that for the three states with an enforced OBD program, at 4 years old, the percentage of tests
with evap DTCs was between 0.2% and 0.8%. At 8 years old, the percentage increased to
between 0.5% and 2.2%, and the rate of increase was approximately 0.15% per year. In
comparison, for state D, at 4 years old the percentage of tests with evap DTCs was between 1.0%
and 2.0%. At 8 years old, the percentage increased to between 2.6% and 4.2%, and the rate of
increase was approximately 0.5% per year.
The two trend lines in the figure could be an approximation of the percentage and rate of
increase of evap DTCs as vehicles age in I/M areas and in non-I/M areas. Again, however, it
should be noted that State D does have an I/M program which includes an OBD test (advisory)
as well as a fuel cap test, so evap DTC rates in State D are likely lower than those in a non-I/M
area. The trend line showed that for the three states with an enforced I/M program, at 4 years old
the approximate percentage of tests with evap DTCs is 0.5%. This percentage increases to
approximately 1.1% for 8 year old vehicles. The increase in the percentage is approximately
0.15% per year. For state D, the trend line shows that the percentage of tests with evap DTCs for
4 year old vehicles is approximately 1.4%, and this increases to approximately 3.5% for 8 year
old vehicles. The increase in the percentage of tests with evap DTCs by age is approximately
0.5%.
State D does include an enforced gas cap test in their I/M program, so the trend line
approximating the non-I/M area (in red) might be a conservative estimate. The trend lines show
that for 8 year old vehicles in an I/M area, approximately 1.0% of them could have a stored evap
DTC, while in a non-I/M area the percent of 8 year old vehicles could be over 3%.
As has been stated earlier, all of the predicted values are based on linear trends, and the
data in these plots do suggest some non-linearity in the relationship. A more in-depth statistical
analysis could be used to refine these predicted evap DTC rates by age in a future analysis.
3.5 Evap DTCs over Multiple Inspection Cycles
In enforced OBD programs, less than 0.5% of the vehicles with a "ready" evap monitor
and with at least one evap DTC were found to have evap DTCs in more than one I/M cycle. This
suggests that it may be more common for evap DTCs to periodically occur throughout the I/M
fleet rather than be limited to a smaller number of "problem" vehicles that repeatedly have evap
DTCs over multiple I/M cycles. However, the distribution of the fleet (in terms of the number of
inspection cycles) will affect the percentage of vehicles with evap DTCs in more than one I/M
35
-------
cycle (older vehicles which have undergone more inspection cycles will be more likely to have
evap DTCs in more than one I/M cycle).
3.6 Evaluation of Evap DTC rates based on the Prior I/M Cycle's Evap Monitor
Readiness Status
For this analysis, the evap DTC rates for "evap ready" vehicles which had a "not ready"
evap monitor in the previous I/M cycle were analyzed. For every state, the evap DTC rates were
between 2% and 10% higher for vehicles that previously had a "not ready" evap monitor in
comparison to the overall fleet. One possible explanation for this is that for some of these
preceding tests in which the evap monitor was not ready, the vehicle's battery had been
disconnected prior to the test in order to extinguish the MIL and pass the I/M inspection, thus
resetting the readiness monitors and clearing the DTCs (possibly evap DTCs) which would
reappear during a subsequent inspection unless that problem had been properly addressed.
Regardless of the cause, these results imply that that the actual rate of vehicles with evap DTCs
may be higher than the DTC rate calculated based on I/M data (i.e., "not ready" evap monitors
may be masking some evap DTCs in the I/M data), but because of the differences among the
states and the small subsample of vehicle tests, additional analysis would be required to
investigate this more fully.
4.0 Most Common Evap DTCs
The graphs in Section 3 present rates of evap DTCs without consideration of the specific
DTC. In this section, the specific evap DTCs that were set in each state were highlighted. This
additional analysis showed the majority of evap DTCs are limited to a small subset of codes.
This section summarizes the most common evap codes, either set individually or in combination
with other evap codes (e.g. codes P0442 and P0455).
4.1 Most Common Individual Evap DTCs
The prevalence of generic (PO) evap codes and manufacturer-specific (PI) codes were
tabulated to identify the trends in individual DTCs (not the multiples in this case). The number of
test records containing each of the individual evap DTCs (listed in Table 4) was summed for
each state. This count was done by DTC, regardless of which other evap DTCs were in the same
test record. Table 6 shows the results of the counts of each evap DTC for each of the states.
Because records with more than one evap DTC were counted more than once, the total number
of test records in Table 6 will exceed the total number of test records with evap DTCs. For
example, a record with 3 evap DTCs will be listed 3 times in Table 6, once for each of the 3
DTCs contained in the test record.

These totals are for 1996 and newer vehicles. They will be larger than the total of evap DTCs presented in
Appendix tables C-l through C-4 and E-l through E-4 because some evap DTCs are set together.

-------
From Table 6, the most common individual DTCs that were in all states combined were
identified. These include PO and PI codes (shaded in gray in the table) with 440, 441, 442, 443,
446, 447, 448, 449, 450, 452, 455, 456, and 457. The results are presented by calendar year and
model year in Appendix D. Because the other evap DTCs were not as common, their
distributions are not presented in Appendix D. The numbers in the Appendix D tables indicate
that as vehicles age, the percentage of vehicles with each particular evap DTC increases slightly.
When reviewing these results, it should be noted that different vehicle makes and models have
different evap monitor readiness and evap DTC rates. Therefore, differences in fleet mix and
fleet age distributions in the various states could be contributing to the differences among states.
Also, as noted previously, environmental conditions such as ambient temperatures and elevation
(ambient pressure) which vary from state to state may also affect evap monitor readiness and
evap DTC rates and contribute to the differences among the state results provided in Appendix
D.
4.2 Most Common Individual Evap DTCs and Evap DTC Combinations
The prevalence of generic (PO) evap codes and manufacturer-specific (PI) codes (either
individually or in combinations) was tabulated. Less than 20 different individual and
combinations of evap codes comprised more than 90% of all evap codes in the data. Appendix E
contains tables showing the most common evap DTCs and evap DTC combinations for each
state. Table 7 lists the most common evap DTCs for all 4 states combined. The DTC definitions
are based on the generic PO codes listed in SAEJ2012 and are listed in Table 4. The percentage
of all codes from all states is listed in Table 7.

Note: These results are for model years 1996 and newer
Table 7 shows that for all the states combined, common codes primarily fall into two
categories, leaks or purge flow. The leak codes, including P_442, P_455, P_456, and P_457,
comprise more than 50% of the overall evap codes for vehicles of model years 1996 and newer.
This number represents a minimum of the percent of the total evap DTCs that involve leaks,
because the four codes listed above are only some of the codes that could indicate a leak in the
evaporative emissions control system. Also, 50% represents the minimum percentage of evap
DTCs that involve leaks, but the percentage of evaporative emissions resulting from these leak-
related DTCs may be higher or lower than 50% of all evaporative emissions, since emission rates
can vary significantly based on type of failure. Some malfunctions may not result in any
evaporative emissions release. This analysis does not attempt to quantify the emission rates from
any specific evap DTCs, it only quantifies the rate of evap DTCs.
The second most common category of evap DTCs in Table 7 involve some sort of error
in the operation of the purge flow control. The codes for these DTCs include P_441 and P_443,
and they make up approximately 15%-20% of the evap DTCs found in the data. Other types of
evap codes include general evap malfunction (P_440), vent control circuit malfunction (P_446),
and pressure sensor (P_450).
The leak codes for each of the states were tabulated by calendar year and model year to
see what percentage of the inspections with evap DTCs had leak-related evap DTCs. The
detailed tables for leaks are also included in Appendix E. The tables show that in a given
calendar year and model year, the percentage of the evap DTCs that are leak-related varies
39
-------
significantly from the overall percentage of over 50% highlighted above. In general, however,
the newer model years have a higher percentage of the evap DTCs being leak-related than the
older model years. In some calendar years and model years, over 75% of the evap DTCs can be
leak-related. This indicates that the overall percentage of 50% of the evap DTCs being leak-
related is a conservative estimate, especially if only newer model years are considered.
5.0 Conclusions
This report presented results from analysis of OBD evap monitor readiness status and
OBD evaporative emissions control system DTCs as a function of calendar year and model year
using I/M program data from four states. The main purpose of this Work Assignment was to
better understand evap monitor readiness and evap DTC rates for light-duty gasoline cars and
trucks. In order to standardize results among all states and minimize the effect of differences in
how State I/M programs are administered, this analysis was performed without regarding to each
state's OBD readiness or OBD pass / fail determinations. Results in this report are based on the
OBD evap monitor readiness status (without regard to the state's I/M readiness determination)
and the presence (or lack of) evap-related DTCs (without regard to MIL command status).
The first part of the analysis involved determining how many vehicles had a "ready" evap
monitor at the time of initial and/or re-test inspection within one inspection cycle. Evap monitor
readiness was evaluated because some evap DTCs may not be set for vehicles with evap system
malfunctions until the evap monitor achieves readiness (i.e., a "not ready" evap monitor can
"mask" some evap system DTCs). The percentage of "not ready" evap monitors was evaluated
and compared among each state, and that analysis showed that all states have similar evap
monitor readiness percentages, even State D which does not perform pass/fail OBD inspections,
they are only advisory.
Regardless of the details of the I/M program administration or the calendar years of data
analyzed, the results suggest that approximately 7-11% of the initial inspections in any given
I/M program are likely to have a "not ready" evap monitor. The similarity in this percentage for
all of the states suggests that this number could approximate a national percentage of vehicles in
I/M programs with a "not ready" evap monitor.
When comparing these results with previous analysis of non-evap OBD monitors, the
percentage of "not ready" evap monitors was much higher than for other OBD monitors. For
example, when evaluating all the OBD monitors' status for one of these states, the non-evap
OBD monitors had an overall "not ready" range of 1% - 2% instead of the 7%-l 1% range seen
for the evap monitor. As the OBD evap monitor is typically subject to more rigorous enabling
40
-------
criteria (specific vehicle operation and soak requirements) than other monitors in order to
achieve readiness, this monitor is generally one of the last monitors to achieve readiness, and
will likely have a higher fleet-wide "not ready" rate than other monitors at any point in time
(such as during an I/M inspection). Due to the longer "not ready" period of the OBD evap
monitor, it is possible that attempts to mask MIL illumination in order to pass an I/M test
(through a battery disconnect or code clearing) or code clearing after legitimate repairs could
contribute somewhat to the lower OBD evap monitor readiness rates seen during I/M tests.
Further analysis indicated that vehicles in an I/M environment (including State D, which
is advisory-only for OBD) are more likely to have a "not ready" evap monitor as they age. Linear
trend lines6 were developed for each of the states showing the percent of inspections with a ready
evap monitor versus vehicle age. This trend line was based on a modified dataset for each of the
states that only included inspections of vehicles that would typically be subject to the I/M
program at the time of their regular inspection. This involved removing inspections in which the
vehicle was too new for the I/M inspection and also removing inspections during an "off year in
the biennial I/M programs. The results showed that as a vehicles age, they will be more likely to
have a "not ready" evap monitor during an I/M cycle. The analysis was conducted by binning all
vehicles in a given age (from 2 to 10 years old in most states). The vehicles at any given age can
have a range of odometer values, so they may not all be in the same condition in terms of wear-
and-tear and mileage.
For all four states, the trend lines showed that between 2% and 4% of the inspections of
vehicles entering the I/M program (at about 2 years old) had a "not ready" evap monitor. The
percentage increased to between 8% and 11% as the vehicles aged to 8 years old, and the rate of
increase was approximately 1% per year as the vehicle ages.
The evap DTC rates for all vehicles with "ready" evap monitors was then analyzed. The
results indicate 0.7%-2.5% of the inspections with "ready" evap monitors have a stored evap
DTC. The results also show that the overall percentage of inspections with a stored evap DTC is
higher for State D (where OBD is not enforced) than for the other states where OBD is enforced.
The percentage of inspections with evap DTCs were also analyzed by calendar year and model
year, and trend lines7 were developed for each of the states showing the percentage of
inspections with evap DTCs versus vehicle age. These trend lines were based on a modified
dataset for each of the states which only included inspections of vehicles that would typically be
subject to the I/M program at the time of their inspection (again, removing vehicles that are "too

-------
new" or not in their biennial test year). For the three states with an enforced I/M OBD program,
between 0.1% and 0.5% of vehicles with "ready" evap monitors entering the I/M program (at
about 2 years old) had an evap DTC. At 4 years old, the percentage of tests with evap DTCs
increased to between 0.2% and 0.8% for those three states. At 8 years old, the percentage
increased to between 0.5% and 2.2%, and the rate of increase was approximately 0.15% per year.
The rate of increase in the percentage of evap DTCs for the fourth state, State D, was
over 3 times higher than the rate of the other three states. For example, at 4 years old the
percentage of tests with evap DTCs was between 1.0% and 2.0% for state D. At 8 years old, the
percentage increased to between 2.6% and 4.2%, and the rate of increase was approximately
0.5% per year. This higher rate of increase of the percentage of evap DTCs by age is likely due
to the fact that OBD is not enforced in State D. It is possible that the percentage of evap DTCs
for State D is indicative of the minimum rate of evap DTCs in a non-I/M area. The rate of
increase in a non-I/M area could be even higher than the slope for State D, because State D does
have an I/M program that includes an evap testing component (gas cap test).
The percentage of evap DTCs set by calendar year and model year were combined for
those three states (States A, B, and C) to calculate a single trend line showing the percentage of
evap DTCs set by vehicle age. The combined State A, B, C trend line was then compared with
the trend line for State D (in which OBD is not enforced) as a comparison of results from states
with an enforced OBD program versus a state without an enforced OBD program. The trend
lines show that the rate of increase of evap DTCs as the vehicles age is over 3 times higher for
State D versus that for the states with an enforced OBD program. For example, the trend line
showed that for the three states with an enforced I/M program, at 4 years old the approximate
percentage of tests with evap DTCs is 0.5%. This percentage increases to approximately 1.1%
for 8 year old vehicles. The increase in the percentage is approximately 0.15% per year. For state
D, the trend line shows that the percentage of tests with evap DTCs for 4 year old vehicles is
approximately 1.4%, and this increases to approximately 3.5% for 8 year old vehicles. The
increase in the percentage of tests with evap DTCs by age is approximately 0.5%. These trend
lines might be used as one way to approximate the rate of stored evap DTCs for vehicles in I/M
and non-I/M areas.
Vehicles with evap DTCs were analyzed over multiple inspection cycles, and less than
0.5% of these vehicles were found to have evap DTCs in more than one I/M cycle. Vehicles with
"not ready" evap monitors throughout one inspection cycle were found to have slightly higher
evap DTC rates during the subsequent inspection cycle, suggesting that "not ready" evap
monitors could be masking evap problems (and hence evap DTCs). However, further analysis
42
-------
showed that less than 3% of the vehicles analyzed had an evap monitor status of "not ready"
more than two times in their entire I/M history.
Further analysis showed that the majority of evap DTCs are limited to a small subset of
codes. The records with individual evap codes as well as multiple evap codes were analyzed, and
the results showed that usually fewer than 20 different individual and combinations of evap
codes comprised more than 90% of all evap codes in the data. The results show that for all the
states combined, common codes primarily fall into two categories, leaks or purge flow. The leak
codes, including P_442, P_455, P_456, and P_457, comprise more than 50% of the overall evap
codes for vehicles of model years 1996 - 2010. This number represents a minimum of the
percentage of the total evap DTCs that involve leaks, because the four codes listed above are
only some of the codes that could indicate a leak in the evaporative emissions control system.
This 50% represents the minimum percentage of evap DTCs that involve leaks, but the
percentage of evaporative emissions resulting from these leak-related DTCs may be higher (or
lower) than 50% of all evaporative emissions, since emission rates can vary significantly based
on type of malfunction.. This analysis does not attempt to quantify the emission rates from any
specific evap DTCs, it only quantifies the rate of evap DTCs.
The second most common category of evap DTCs in the data involved some sort of error
in the operation of the purge flow control. The codes for these DTCs included P_441 and P_443,
and they made up approximately 15%-20% of the evap DTCs found in the data.
The newest vehicles in every state are not subject to the I/M program and therefore are
not included in this analysis. The evap monitor readiness status decreases and evap DTC rates
increase as vehicles age. It is likely the evap monitor "not ready" rates and the evap DTC rates
presented in this report are actually higher than those that would be seen for the entire on-road
vehicle fleet. The newer vehicles would make up a high percentage of the fleet but would have
lower percentages of "not ready" evap monitors and stored evap DTCs. The vehicles analyzed
from each state for this report are all subject to an I/M program. Since the State D program is
advisory for OBD, it was used in this report to approximate OBD evap fleet trends from a non-
I/M area, but it is likely to be a "best-case" scenario (lower evap DTC rates than a non-I/M area)
since State D does provide OBD results on an advisory basis and it does have an enforced gas
cap test.
For future work, data from another source (such as some commercially available database
of on-road vehicle data monitoring) could be obtained to further develop estimates of the evap
43
-------
monitor status and DTC rates for new vehicles and vehicles operating outside of I/M programs
(as these vehicles are not currently well represented in this analysis of I/M data).
Future work could also involve evaluation of on-road I/M pullover testing to determine
the evap DTC and evap monitor readiness rates for in-use vehicles and compare these rates with
the I/M rates presented in this report. Other future work could also involve performing analysis
of DTCs and readiness of monitors associated with engine operation (i.e., exhaust emissions) and
compare these rates with the evaporative emissions control system rates presented in this report.

Appendix A
Summary of Data Filters Applied the States' Data
-------
For all the states' data, filters were applied to the data to remove any inspection records
that should not be used for this analysis. This included inspections of heavy duty vehicles
(vehicles with a gross vehicle weight rating (GVWR) greater than 8500 Ibs), inspections of
vehicles with a fuel type other than gasoline, invalid or unofficial test records, audits and special
inspections performed at government-operated stations (in the states where this is applicable).
Any records with obviously invalid VINs, such as VINs of "TEST", "OBDTEST",
"OBD2TEST", "12345", "000" and "111", were removed. Then any vehicle tests with a result of
"Abort" were removed. These aborted tests do not have any valid OBD results, so they were
removed before beginning the identification of initial tests. Also, for the purposes of this
analysis, all vehicles 1995 and older were removed from the dataset, and records with invalid
model years were removed. Only records where the inspection record indicated that an OBDII
inspection had been performed (i.e., test type=OBD, OBD result=P or F, malfunction indicator
light (MIL) status=P or F, diagnostic link connector (DLC) result=P) were kept. In addition, any
tests where the inspection reason indicated that the record was for a safety-only inspection and
any other tests where an OBD inspection was not required were dropped. Finally, in some states,
a few vehicles were found to have received hundreds of inspections, often with three or more
inspections on the same day; these appear to be audit vehicles, and since they do not represent
actual vehicles from the I/M fleet, they were also deleted.
