The CMP sensor are located in the camshaft cover. They are each sealed with an O ring seal and secured in the cover with a bolt.
Each CMP sensor is located above a sensor ring on each camshaft. The sensor determines the position of the camshaft by a gap in the sensor ring and passes this information to the ECM. The ECM uses this information and position data from the CKP sensor to determine the current position of the crankshaft and camshafts. This is used for a number of engine functions including VCT operation, fuelling and ignition timing.
