The ECM (Engine Control Module) monitors and correlates the desired intake manifold setting valve values. This valve has the purpose of contributing to the performance and driveability of the vehicle. It performs this activity by regulating the pressures between the manifold gaskets. Besides, it redirects the air to a separate set of intake channels to change the flow and increase the engine’s performance.
Because this valve is primarily made of plastic, it can fail when exposed to high engine temperatures.
When the DTC code P0660 OBDII is set, it is because there is an electrical failure which has been detected by the ECM. This fault is in bank number 1.
