Camshaft Position Sensor: Testing and Inspection

The CMP sensor senses the camshaft position sensor on compression stroke of the No.1 and No.4 cylinders, converts it into a pulse signal, and inputs it to the ECM. The ECM then computes the fuel injection sequence, etc. based on the input signal.

TROUBLESHOOTING HINTS
If the CMP-Sensor does not operate correctly, correct sequential injection is not made so that the engine may stall or run irregularly at idle or fail to accelerate normally.
