Camshaft Position Sensor: Description and Operation
Fig 4 Camshaft Position Sensor
CAMSHAFT POSITION SENSOR-PCM INPUT
The camshaft position sensor provides cylinder identification to the Powertrain Control Module (PCM). The sensor generates pulses as groups of
notches on the camshaft sprocket pass underneath it. The PCM keeps track of crankshaft rotation and identifies each cylinder by the pulses
generated by the notches on the camshaft sprocket.
When metal aligns with the sensor, voltage goes low (less than 0.3 volts). When a notch aligns with the sensor, voltage spikes high (5.0 volts). As
a group of notches pass under the sensor, the voltage switches from low (metal) to high (notch) then back to low. The number of notches determine
the amount of pulses. If available, an oscilloscope can display the square wave patterns of each timing events.

The camshaft position sensor is mounted in the front of the timing case cover.
