Camshaft Position Sensor: Testing and Inspection

CAMSHAFT POSITION (TDC) SENSOR




The TDC Sensor is a Hall-effect sensor that detects the camshaft position on the compression stroke to the No.1 cylinder, 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 TDC Sensor does not operate correctly-sequential injection is may not occur and the engine may stall or run irregularly at idle or fail to accelerate normally.
