The CMP sensor provides the camshaft position information, called the CMP signal, which is used by the Powertrain Control Module (PCM) for fuel synchronization.
The following vehicles do not utilize a CMP sensor:
1994 2.3L engines equipped with a manual transmission, all 1995–97 2.3L and 1998 2.5L engines utilize a CMP sensor that is located on the oil pump cover assembly, on the left-hand lower side of the engine block.
On the 1994 3.0L engine in the B Series Pick-up and 1996–98 MPV, the CMP sensor is an integral component of the distributor assembly, and it is a Hall effect magnetic switch.
On 1995–98 3.0L (B Series Pick-up) and 4.0L engines, the CMP sensor is mounted on an auxiliary shaft drive assembly, located towards the rear of the block. it is also a single hall effect magnetic switch and it is activated by a single vane, and is driven by the camshaft.
