DTC P0661:00: Notes

DTC P0661:00	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 the variable intake air solenoid valve off but the voltage still remains low, the PCM determines that the variable intake air solenoid valve circuit has malfunction. Diagnostic support note This is a continuous monitor (other). The MIL does not illuminate. FREEZE FRAME DATA (Mode2)/Snapshot data is not available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	Variable intake air solenoid valve connector or terminal malfunction Short to ground or open circuit in variable intake air solenoid valve power supply circuit Short to ground in wiring harness between variable intake air solenoid valve terminal A and main relay terminal D ENGINE 10 A fuse malfunction Open circuit in wiring harness between variable intake air solenoid valve terminal A and main relay terminal D Variable intake air solenoid valve malfunction Short to ground in wiring harness between variable intake air solenoid valve terminal B and PCM terminal 2J PCM connector or terminal malfunction Open circuit in wiring harness between variable intake air solenoid valve terminal B and PCM terminal 2J PCM malfunction
