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

LOCATION
The camshaft position sensor is located on the rear cylinder bank in front of the exhaust camshaft. The camshaft position sensor extends into the rear cylinder head and is sealed with an O-ring.

DIAGNOSTIC NOTE
The camshaft sensor is not adjustable.
