Camshaft Position Sensor: Testing and Inspection

CAMSHAFT POSITION SENSOR
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.

Harness Inspection Procedure [DOHC 2.4]:

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.
