Camshaft Position Sensor: Testing and Inspection

CAMSHAFT POSITION SENSOR
Camshaft position sensor (CMP Sensor) senses the TDC point of No.1 cylinder in its compression stroke, whose signals are fed to ECM to be used to determine the sequence of the fuel injection.

TROUBLESHOOTING HINTS
1. If the camshaft position sensor does not operate correctly, correct sequential injection does not occur so the engine may stall or run irregularly at idle or fail to accelerate normally.
2. The MIL is ON or the DTC is displayed on the HI-SCAN under the following condition;
1. When the CMP sensor does not detect any signals though the crank shaft finished its 2 revolutions.
