Camshaft Position Sensor

The camshaft position sensor is located on rear cylinder back in front of exhaust camshaft. The camshaft position sensor extends into rear cylinder head and is sealed with an O-ring. The camshaft position sensor is not adjustable.

As rear cylinder bank exhaust camshaft turns, a steel pin on its drive sprocket passes over magnetic camshaft position sensor. This creates an "ON-OFF-ON-OFF" signal sent to ignition control module similar to crankshaft position sensors. The camshaft position sensor produces one "ON-OFF" pulse for every one revolution of camshaft or every two revolutions of crankshaft. This allows ignition control module to recognize camshaft position.
