| P2401 |
Leak detection pump stuck OFF |
P043E, P043F, P2401, P2402 and P2419 present when one of following conditions met during key-off EVAP monitor:
- EVAP pressure just after reference pressure measurement greater than -1 kPa-g (-7.5 mmHg-g)
- Reference pressure less than -4.85 kPa-g (-36.4 mmHg-g)
- Reference pressure greater than -1.057 kPa-g (-7.93 mmHg-g)
- Reference pressure not saturated
- Reference pressure difference between first and second 0.7 kPa-g (5.25 mmHg-g) or more
HINT:
Typical example values |
- Canister pump module (Reference orifice, leak detection pump, vent valve)
- Connector/wire harness (Canister pump module-ECM)
- EVAP system hose (pipe from air inlet port to canister pump module, canister filter, fuel tank vent hose)
- ECM
