Camshaft Position Sensor

TOP DEAD CENTER (TDC) SENSOR




The TDC sensor senses the top dead center on compression stroke of the No.1 and No.4 cylinders, converts it into a pulse signal and inputs it to the ECU. The ECU which then computes the fuel injection sequence, etc. based on the input signal.

Troubleshooting Hints
If the TDC 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.
