Camshaft Position Sensor: Service and Repair
Cam Position Sensor
The cam position sensor is a Hall effect switch located in the distributor. It provides one pulse per rotation of the distributor. The Powertrain Control
Module (PCM) uses the cam sensor signal to know the location of the camshaft for proper fuel distribution. PCM code P041 will set if the computer
receives reference pulses and does not detect a cam sensor pulse.
