Camshaft Position Sensor: Description and Operation

Camshaft Position Sensor (TDC):

CAMSHAFT POSITION SENSOR (TDC)
The TDC is a Hall-effect sensor that detects the camshaft position on the compression stroke of the No.1 cylinders, converts it into a pulse signal, and inputs it to the ECU. The ECU then computes the fuel injection sequence, etc. based on the input signal.
