Camshaft Position (CMP) Sensor
The CMP sensor detects the position of the camshaft. The CMP sensor identifies when piston number 1 is on its compression stroke. A signal is then sent to the PCM and used for synchronizing the sequential firing of the fuel injectors. Coil on plug (COP) ignition applications use the CMP sensor signal to select the correct ignition coil to fire.
Engines with 1 camshaft and VCT are equipped with 1 CMP sensor. The sensor identifies the camshaft position.
The 1 sensor system on engines with 1 camshaft and with VCT use the following CMP sensor signal circuit names: CMP11 - bank 1, sensor 1.
