| P2401 |
Leak detection pump stuck OFF |
P043E, P043F, P2401, P2402 and P2419 are present when one of the following conditions is met during key-off EVAP monitor:
- EVAP pressure just after reference pressure measurement greater than -1 kPa-g (755 mmHg-a)
- Reference pressure less than -4.85 kPa-g (726 mmHg-a)
- Reference pressure greater than -1 kPa-g (755 mmHg-a)
- Reference pressure is not saturated
- Reference pressure difference between first and second is 0.7 kPa-g (5 mmHgg) or more
HINT:
These values are typical |
- Canister pump module (reference orifice, leak detection pump, vent valve)
- Connector/wire harness (canister pump module - ECM)
- ECM
|
Ignition switch OFF |
2 trip |
