1997 Plymouth Grand Voyager Question: camshaft position sensor
Answer #1Johnny Mopar April 07, 2011, 15:07Master
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.
The 3.0L engine is equipped with a camshaft driven mechanical distributor, containing a shaft driven distributor rotor. The distributor is also equipped with an internal camshaft position (fuel sync) sensor Camshaft Position Sensor - 3.0L Engine This sensor provides fuel injection synchronization and cylinder identification to the PCM.
The camshaft position sensor contains a hall effect device callled a sync signal generator. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 through the sync signal generator. Its signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders. The Camshaft Position Sensor is not serviced separately and is serviced as a Distributor Assembly Part #MD305060. Check with your local Dodge or Mitsubishi dealership for current prices. Labor time to replace and Adjust Ignition timing is .7 hour.
