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 camshaft position 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.
