Camshaft Position Sensor: Description and Operation
Description
DESCRIPTION
The camshaft position sensor is located on the rear cylinder bank (BANK 1) in front of the exhaust camshaft. The camshaft position sensor extends into
the rear cylinder head and is sealed with an O-ring.
OPERATION
The camshaft position sensor is not adjustable. 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.
