Camshaft Position Sensor: Description
On 2.0/2.4L engines the camshaft position sensor attaches to the rear of the cylinder head. On 1.6L engines it is mounted on the front side of the cylinder head. The PCM determines fuel injection synchronization and cylinder identification from inputs provided by the camshaft position sensor and crankshaft position sensor. From the two inputs, the PCM determines crankshaft position. See Fig 1.
