Camshaft Position (CMP) Sensor (Top Dead Center (TDC) Sensor)
The CMP (TDC) sensor detects the position of the No.1 cylinder as a reference for sequential fuel injection to each cylinder.



  1. Remove the grommet from the upper cover, and disconnect the camshaft position (CMP) (top dead center (TDC) ) sensor connector. graphic
