Engine Performance problem
1994 Dodge Intrepid 6 cyl Front Wheel Drive Automatic 120000 miles
According to the shop manual, the PCM wont turn on the following relays ( Fuel Pump, Auto ShutOff ) if a signal is not recieved from the cam and crank position sensors when the key is turned to the on position.
DMM shows no 12V at the relay coils so it seems like either the PCM died, or the crank or camp position sensors.
I am fluent with a DMM and an oscilliscope. I know an oscilliscope can be used to check for the squarewave coming from the sensors. The cam sensor has 3 wires. How can I get a pinout for the sensor - or better yet, how do I test it to find out if its bad? Same with the PCM. Also, anyone ever replaced the crank sensor? It looks really difficult to get to.
have the same problem?
