Camshaft Position Sensor: Description
WARNING: This page is about a different car, the 2005 Dodge SX, 2005 Dodge SRT-4, and 2005 Dodge Neon. However, it is still accessible from the selected car via links, so may be relevant.
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.
