DTC P2676: Notes
DTC P2676 DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P2676 |
Variable air duct (VAP) solenoid valve circuit low 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 off, but the voltage of the VAD solenoid valve control signal remains low.
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 off but voltage still remains low, 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
- Open circuit in wiring between main relay and VAD solenoid valve terminal A
- Open circuit in wiring between VAD solenoid valve, terminal B and PCM terminal 1K
- Short to ground in wiring between VAD solenoid valve terminal B and PCM terminal 1K
- Connector or terminal malfunction
- PCM malfunction
