EVAPORATIVE EMISSION CONTROL SYSTEM LEAK DETECTED
| DTC No. | Monitoring Items | Malfunction Detection Conditions | 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 0.2], ECM determines that EVAP system has large leak. |

While ignition 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. |
