Camshaft Position Sensor: Description and Operation
PURPOSE
The Camshaft Position Sensor is a Hall Element type unit which sends signals to the ECM which are used to determine ignition and injector
timing.
OPERATION
The camshaft position sensor senses the top dead center on compression stroke, converts it into a pulse signal and inputs it to the engine control
module, which then computes the fuel injection sequence, etc. based on the input signal.
Power to the camshaft position sensor is supplied from the multiport fuel injection relay and is grounded to the body. The camshaft position sensor
generates a pulse signal as it repeatedly connects to and disconnects from the 5 V voltage supplied from the engine control module and ground.
