| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
|---|---|---|---|---|---|---|
| P0455-00 | Evaporative Emission System Leak Detected (Large Leak) | Leak detection pump creates negative pressure (vacuum) in EVAP system and EVAP system pressure is measured. Reference pressure is measured at start and end of leak check. If stabilized pressure is higher than [second reference pressure x 0.2], ECM determines that EVAP system has a large leak. |

| P0456-00 | Evaporative Emission System Leak Detected (Very Small Leak) | Leak detection pump creates negative pressure (vacuum) in EVAP system and EVAP system pressure is measured.
