CKP (Cylinder Position) Sensor

Fig. 38 Crank Angle Sensor And Output Waveform Chart:

The sensor consists of a pair of rotors, TDC and CYL, and a pickup coil for each rotor. Since the rotors are coupled to the cam shaft, they turn together as a unit as the cam shaft rotates. The CYL sensor detects the position of the number 1 cylinder as the base for the sequential injection. The TDC sensor serves to determine the injection timing for each cylinder. The TDC sensor also supplies the rpm signal to the ECU.
