DTC P2405: Notes
DTC P2405 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P2405 |
EVAP system leak detection pump sense circuit low input |
| DETECTION CONDITION |
- The PCM monitors the pump load current (EVAP line pressure) when the EVAP leak monitor is operating. If the current is lower than the specification when the PCM obtains the reference current value, the PCM determines that the EVAP system leak detection pump orifice has malfunction.
Diagnostic support note
- This is an intermittent monitor (CCM).
- MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
- PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA is available.
- DTC is stored in the PCM memory.
