Camshaft Position Sensor (2.4L)
Camshaft position sensor may be referred to as Camshaft Position (CMP) sensor. Camshaft position sensor is located on rear of cylinder head, just below valve cover. See Fig 1 . Camshaft position sensor uses a target magnet attached to rear of camshaft and uses locating dowels for proper positioning. See Fig 2 .
As target magnet rotates, camshaft position sensor senses the change in the polarity. The polarity change causes camshaft position sensor output voltage to switch from high-voltage of 5 volts to a low-voltage of .3 volt. Camshaft position sensor delivers input signal to Powertrain Control Module (PCM). PCM uses this input signal along with input signal from crankshaft position sensor for determining crankshaft position for fuel injection synchronization and cylinder identification.
