Camshaft Position Sensor: Description and Operation
The sensor is mounted on the sensor case (distributorless ignition case) on the camshaft left side. The signal rotor is press-fitted onto the camshaft. As the
sensor has a built-in hall element (element which generates voltage from changes in the magnetic flux) and a waveform forming circuit, it converts
changes in the magnetic flux caused by rotation of the signal rotor into electric pulse signals. Using this signal and the signal from the CKP sensor, ECM
(PCM) identifies the cylinder whose piston is in the compression stroke.
