DTC P2405: Notes
DTC P2405 DETECTION & CONDITION POSSIBLE CAUSES
| DTC P2405 |
EVAP system leak detection pump sense circuit low |
| DETECTION CONDITION |
- The PCM monitors the pump load current (EVAP line pressure) when the evaporative leak monitor is operating. If the pump load current is less than the specification while the PCM obtains the reference current value, the PCM determines that the EVAP system leak detection pump sense circuit voltage is low.
Diagnostic support note
- This is an intermittent monitor (EVAP system).
- The 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.
- The DTC is stored in the PCM memory.
