Crankshaft Position (CKP) Sensor: Notes

The Crankshaft Position Sensor is a Hall-effect sensor that senses the Crank angle (piston position) of each cylinder and converts it into a pulse signal. Based on the input signal, the ECU computes the engine speed and controls the fuel injection timing and ignition timing.
