DTC SUMMARY CHART
| DTC No | Monitoring Item | Malfunction Detection Condition | Trouble Area | Detection Timing | Detection Logic |
|---|---|---|---|---|---|
| P0455 | EVAP gross leak | Leak detection pump creates negative pressure (vacuum) in EVAP system and EVAP system pressure measured Reference pressure measured at start and at end of leak check If stabilized pressure higher than [second reference pressure x 0 32], ECM determines that EVAP system has large leak |
|
While engine switch off | 2 trip |
| P0456 | EVAP small leak | Leak detection pump creates negative pressure (vacuum) in EVAP system and EVAP system pressure measured Reference pressure measured at start and at end of leak check If stabilized pressure higher than second reference pressure, ECM determines that EVAP system has small leak |
