Hello and welcome to just answer. Sounds like you have a failed PCM. If you are certain that the wiring between the sensor and the PCM is ok and not shorted to voltage and is not open, then it has to be the PCM. I do see that every now and then at the dealer I work at.Chris

I don't fully understand the service information i have available and Chrysler operates this system differently than what i am used to by supplying voltage to the sensors. is there any tests i can perform to verify that this is a pcm failure
