Camshaft Position Sensor (2.2L & 2.4L)
Camshaft Position (CMP) sensor is located on rear side of engine block (2.2L), or on top of cylinder head in camshaft housing (2.4L). CMP sensor is used to determine crankshaft-to-camshaft position so that PCM can determine which cylinder is ready to be fueled by injector. Sensor is also used to determine which cylinder is misfiring when a misfire is present. A problem in the circuit will set a related diagnostic trouble code.
