Reference voltage come from the PCM to the HO2S sensors and on bank 1 sensor #2 the power feed at the PCM is pin 17 (Brown/violet) . Is that the wire and pin your checking?
Okay that in most cases means the problem is with the PCM if the wire ohms out okay. That being said I would go back and recheck it once more to be sure with the factory steps I have enclosed in the link below. If you find the same results then suspect the PCM.
I would just to be sure. Thank you as well. Please take a moment to rate my service so I can get credit for my time, the question remains open for follow up even after doing so, all you need to do is return to this question if need be.
Thank you again.
The Z904 is the Ground 109 located at the shock tower, see the location in this link.
See the pcm verification test in this link.
From reading your results and providing you have done your testing right it sure dose look like the PCM is at fault here.
Unfortunately with out being have to have a look at it I do not know where it would go. It could just be a connector for something your car is not equipped with.
I have no control over what type of plan you have. You will need to contact customer support for any questions you have on this . Thank you as well.
Chrysler only offers wiring for the circuits and dose not offer any for the Harness as a whole. If you know the circuit I can provide a wiring diagram.
There are a total of 5 wiring diagrams for the engine control system. See them in the links below and see if you can see the wires in question.
Your very welcome and thank you as well.
One other cause for the cam codes your getting to set can be cause by cam timing, are you sure the timing is aligned correctly and your chain has not jumper?
In most cases it would not. If you did not have these codes before the ECM replacement them I would wonder if the replacement PCM is defective.
If you clear them out do the return?
Splice S110 is the ground supplied to the sensors from the PCM See the link below for the wiring diagram.
