DTC Description
DTC DETECTION LOGIC
| DTC | CONSULT screen terms (Trouble diagnosis content) | DTC detection condition | ||
| P0451 | 00 | EVAP SYS PRES SEN (Evaporative emission system pressure sensor/switch range/ performance) | Diagnosis condition | - |
| Signal (terminal) | EVAP control system pressure sensor signal | |||
| Threshold | ECM detects a state that the pressure difference remains the threshold value or more for continuously for 5 seconds or more under the condition that the pressure of the EVAP control system pressure sensor and that of the ECM (built-in barometric pressure sensor) are equal. | |||
| Diagnosis delay time | - | |||
POSSIBLE CAUSE
- Harness or connectors (EVAP control system pressure sensor circuit is shorted.)
- EVAP control system pressure sensor
- ECM (built-in barometric pressure sensor)
