Evaporative Emission Control System Incorrect Purge Flow |
One of the following conditions met:
- Leak detection pump creates negative pressure (vacuum) in EVAP system and EVAP system pressure measured. Reference pressure is measured at start and at end of leak check.
If stabilized pressure higher than [second reference pressure x 0.2], ECM determines that purge VSV stuck open.
- After EVAP leak check performed, purge VSV turned on (open), and atmospheric air introduced into EVAP system. Reference pressure is measured at start and at end of check.
If pressure does not return to near atmospheric pressure, ECM determines that purge VSV stuck closed.
- While engine running, following conditions successively met:
- Negative pressure not created in EVAP system when purge VSV turned on (open)
- EVAP system pressure change less than 0.15 kPa(gauge) [1.125 mmHg(gauge)] when vent valve turned on (closed)
- Atmospheric pressure change before and after purge flow monitor less than 0.1 kPa(gauge) [0.75 mmHg(gauge)]
