DTC P0661: Notes

DTC P0661 [L3] DETECTION CONDITIONS AND POSSIBLE CAUSES

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 still remains low for 5s , 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. The FREEZE FRAME DATA (Mode 2/Mode12) is not available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	Variable intake air solenoid valve connector or terminal malfunction Variable intake air solenoid valve malfunction Open circuit in the wiring harness between the main relay and variable intake air solenoid valve terminal B Short to ground in the wiring harness between variable intake air solenoid valve terminal A and PCM terminal 2J PCM connector or terminal malfunction Open circuit in the wiring harness between variable intake air solenoid valve terminal A and PCM terminal 2J PCM malfunction
