Sensor-Camshaft Position -2.8LTD
The camshaft position (CMP) sensor is a hall effect switch. A tooth made of a ferromagnetic material is attached to the camshaft. When this tooth passes the CMP sensor an electronic signal is created. This signal is then sent to the engine control module (ECM). This signal is used by the ECM to determine TDC and which cylinder has just entered its compression phase.
