DTC P2404: Notes
DTC P2404 DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P2404 |
EVAP system leak detection pump sensor circuit malfunction |
| DETECTION CONDITION |
- The PCM monitors pump load current (EVAP line pressure), while EVAP leak monitor is operating. After obtaining the reference current value, if the time in which the pump load current reaches the reference current value is less than the specification, the PCM determines air filter has a malfunction.
Diagnostic support note
- This is a intermittent monitor (CCM).
- MIL illuminates if PCM detects above malfunction condition in two consecutive drive cycles or in one drive cycle while DTC for the same malfunction has been stored in PCM.
- PENDING CODE is available if PCM detects the above malfunction condition during first drive cycle.
- FREEZE FRAME DATA is available.
- DTC is stored in PCM memory.
