| DTC P0661 |
Variable intake air solenoid valve circuit low input |
| DETECTION CONDITION |
- The PCM monitors the variable intake air solenoid valve control signal. If the PCM turns variable intake air solenoid valve off but voltage at PCM terminal still remains low, the PCM determines that variable intake air solenoid valve circuit has malfunction.
Diagnostic support note
- This is a continuous monitor (Other).
- The MIL does not illuminate.
- PENDING CODE is available if the PCM detects the above malfunction condition.
- The FREEZE FRAME DATA is available.

| POSSIBLE CAUSE |
- Variable intake air solenoid valve malfunction
- Open circuit in wiring harness between main relay and variable intake air solenoid valve terminal A
- Open circuit in wiring harness between variable intake air solenoid valve terminal B and PCM terminal 2J
- Short to ground in wiring harness between variable intake air solenoid valve terminal B and PCM terminal 2J
- Connector or terminal malfunction
