Camshaft Position Sensor (C(3)I)

The 3.8L C(3)I models use a Hall Effect camshaft position sensor. The cam sensor provides PCM with a TDC No. 1 signal used to compute the exact position of valves. This allows PCM to properly time ignition and fuel injection. A fault in the cam sensor circuit (no cam sensor signal) will result in a no-start condition and should set a related trouble code.
