DTC P2677: Notes
DTC P2677 DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P2677 |
Variable air duct (VAD) solenoid valve circuit high input |
| DETECTION CONDITION |
California emission regulation applicable ATX model
- The PCM monitors the VAD solenoid valve control signal voltage and current. If the following conditions are met, the PCM determines that there is the VAD solenoid valve circuit problem.
- The PCM turns the VAD solenoid valve on, but the current of the VAD solenoid valve control signal remains high.
Diagnostic support note
- This is a continuous monitor (Other).
- MIL does not illuminate.
- PENDING CODE is available if PCM detects the above malfunction condition.
- FREEZE FRAME DATA is not available.
- DTC is stored in the PCM memory.

Except for California emission regulation applicable ATX model
- The PCM monitors VAD solenoid valve control signal. If the PCM turns VAD solenoid valve on but voltage still remains high, the PCM determines that VAD solenoid valve circuit has malfunction.
Diagnostic support note
- This is a continuous monitor (Other).
- MIL does not illuminate.
- PENDING CODE is available if PCM detects the above malfunction condition.
- FREEZE FRAME DATA is not available.
- DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- VAD solenoid valve malfunction
- Short to power supply between VAD solenoid valve terminal B and PCM terminal 1K
- Shorted VAD solenoid valve or PCM connector
- PCM malfunction
