Camshaft Position (TDC) Sensor: Notes

The TDC sensor 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.
