Camshaft Position Sensor: Description and Operation

The camshaft position sensor is mounted at the rear of Bank 2 cylinder head on the intake side and provides one signal every 720° of crankshaft rotation. The signal, in conjunction with the signal from the crankshaft position sensor, indicates to the ECM that the piston of cylinder 1A is approaching TDC on the compression stroke.

The camshaft sensor is located at the rear of Bank 2 cylinder head and is triggered by a single toothed sensing ring installed to the rear of the intake camshaft. The camshaft sensor is a variable reluctance sensor that provides an input to the ECM of intake camshaft position.
