Camshaft Position Sensor (CMP)
Camshaft Position Sensor (CMP)

The CMP sensor provides the camshaft position information, called the CMP signal, which is used by the Powertrain Control Module (PCM) for fuel synchronization.

On 2 wire Sensor engines, the distributor stator or Camshaft Position (CMP) sensor is a single Hall effect magnetic switch. This is activated by a single vane, and is driven by the camshaft.

On Three Wire Sensor engines, the Camshaft Position (CMP) sensor is a variable reluctance sensor, which is triggered by the high-point mark on one of the camshaft sprockets.
