Variable Valve Timing Actuator Position Sensor: Description and Operation




The intake valve timing control position sensor is located rearmost of the left-bank cylinder head. This sensor detects a signal (intake valve position) generated by the cutout portion of camshaft and sends it to the ECM. This sensor is not used to control the engine system. It is used only for the on board diagnosis of intake valve timing control.
