Code Enable Criteria
PCM commands EVAP purge solenoid off once system has reached a predetermined level of vacuum. This test checks if vacuum can be achieved in EVAP system. Failure to develop a vacuum may be caused by a large leak or restriction. This DTC sets after twice failing this test.
For DTC to run, the following conditions must be met:
- DTCs P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0125, P0440, P0443, P0449, P0452, P0453, P1106, P1107, P1112, P1114, P1120, P1220, or P1221 are not set.
- Ignition voltage is 10-18 volts.
- Barometric pressure (BARO) is more than 75 kPa.
- Fuel level is 15-85 percent.
- Engine Coolant Temperature (ECT) is 39-86°F (4-30°C).
- Intake Air Temperature (IAT) is 39-86°F (4-30°C).
- Start-up ECT and IAT are within 16°F (9°C) of each other.
DTC will set when EVAP system can achieve vacuum, but a vacuum decay is detected during diagnostic test.
