Camshaft Position Sensor (4.6L)

Camshaft Position (CMP) sensor is located on rear cylinder bank in front of exhaust camshaft. Sensor extends into rear cylinder head and is sealed with an "O" ring. CMP sensor is not adjustable.

As rear cylinder bank exhaust camshaft turns, a steel pin on its drive sprocket passes over the magnetic CMP sensor. This creates an on/off signal sent to ignition control module similar to crankshaft position sensors. Sensor produces on/off pulse for every one revolution of camshaft or every 2 revolutions of crankshaft. This allows ignition control module to recognize camshaft position.
