Refer to DTC P0441. See DTC P0441: EVAPORATIVE EMISSION CONTROL SYSTEM INCORRECT PURGE FLOW, DTC P0446: EVAPORATIVE EMISSION CONTROL SYSTEM VENT CONTROL CIRCUIT, DTC P2418: EVAPORATIVE EMISSION SYSTEM VALVE CONTROL CIRCUIT/OPEN .
Scheme 220
- The vehicle must be cold, and ambient temperature is between approximately 10°C (50°F) and 35°C (95°F).
- Intake Air Temperature (IAT) and Engine Coolant Temperature (ECT) sensors indicate almost the same value.
- Clear DTCs. Disconnect the battery terminals or EFI fuse for more than 60 seconds. READINESS TESTS will show INCMPL (incomplete).
- Drive the vehicle on a freeway. Write down the state of READINESS TESTS. They will change to COMPL as the evaluation monitors operate and if the system passes. This procedure may take approximately 20 minutes or more. NOTE: Do not shut off the engine - the results will be invalid.
Pass Condition - No Problem Found by the ECM
If the EVAP evaluation monitor shows COMPL, go to the NON-CONTINUOUS TESTS screen.
Note. Do not shut off the engine - the results will be invalid.
Scheme 221
Scheme 222
- To get there, go to Advanced OBD II, Onboard Tests, NON-CONTINUOUS TESTS.
- If all of the tests in the time $02 category Tests show "Pass", the evaluation monitor has operated and no problem was detected.
Fail Condition - Problem Detected in the ECM
If the EVAP evaluation monitor shows INCMPL, go to the NON-CONTINUOUS TESTS screen.
Scheme 223
Scheme 224
Scheme 225
- If all tests show "Pass", the following may have occurred. The EVAP evaluation monitor did not operate. The EVAP evaluation monitor did not finish. The ECM withheld judgement.
- If one or more tests in the time $02 category show "Fail", the EVAP evaluation monitor did operate and the ECM detected a problem.
- Go to CONTINUOUS TESTS screen. This is the only place where first trip DTC's are listed. NOTE: The listed DTCs may not be valid. A second trip is needed to confirm the DTCs.
Scheme 226
- The vehicle must be cold, and the ambient temperature is between approximately 10°C (50°F) and 35°C (95°F).
- Go to READINESS TESTS screen.
- Drive the vehicle on a freeway. Write down the state of the EVAP evaluation monitor. This procedure may take approximately 20 minutes or more. NOTE: Do not shut off the engine - the results will be invalid.
If READINESS TESTS changes to COMPL, the EVAP evaluation monitor has operated. Check for any stored DTCs.
Scheme 227
- If a DTC Is stored, the problem has been detected and confirmed by the ECM.
- If no DTC Is found, the EVAP monitor has operated but no problem Is detected.
