Camshaft Position Sensor: Description and Operation
Operation
Operation
The CMP sensor (3) contains a signal generator hall switch (2). A signal rotor (2), with 11 notches, is located in the CMP sensor housing and is driven
by the camshaft. The CMP sensor has a specified air gap between the sensor core end and the signal rotor. When the signal rotor in the housing turns, a
magnetic flux from the magnet is applied to the hall element repeatedly. The hall element generates a voltage that is proportional to the magnetic flux.
This voltage signal is wave-shaped and is modified into a digital pulse before being sent to the PCM. The PCM uses the pulse and/or revolution signal in
determining the engine speed and the position of each cylinder.
