Camshaft Position Sensor: Locations

This model does not use a camshaft position sensor.

The following is from DTC P0341.
The EI module uses capacitive pickup plates located under the 1/4 coil pack to determine the polarity sequence and voltage amplitude of the cylinder 1/4 secondary ignition. The PCM supplies 5 volts on the signal line and expects to see the cylinder #4 signal wire go low after every 14 crankshaft pulses (2 revolutions). This is used to determine the position of the camshaft, except under decel. The PCM only uses the transition from 5 to 0 volts as a valid TDC compression #4 cylinder signal.
