A Crank Angle Sensor or a Cam Angle Sensor is a sensor to detect the rotation of a crank or a cam shaft respectively. A Crank Angle Sensor detects the reference position and the rotation angle of a crank shaft and the engine speed. A Cam Angle Sensor is used to determine each cylinder providing a signal to determine the cylinder.

The cam angle sensor is used to distinguish between the individual cylinders. A gear is attached to the camshaft to identify each cylinder, and a sensor detects the distance to the gear projection. A Crank Angle Sensor or a Cam Angle Sensor receives changing magnetic flux due to the rotation of a rotor having a projection. It converts the flux change to a rectangular pulse signal and send it to ECU.
