Engine light came on and got codes above. Codes will not clear. Based on what I read it sounds like one could be caused by the other. Believe it has something to do with PCM. Guys at parts stores tell me they never or rarely go bad and to look for wiring or grounding issue. Part is expensive (275.00) and non-returnable. What do you guys think and can you tell me where this thing is? I cant find it.

The PO601 is most likely the issue here. In most cases this means the PCM has gone bad. This is usually due to a short-circuit inside the PCM, or if you disconnected the wires/connector from the PCM while the battery was still connected. Chances are the PO107 is the result of the PCM. Basically, the code is set by a serial communication failure inside the computer at least 6 times. Chrysler products are known to have this issue; however, it happens to all. You may get lucky and a dealer may be able to get a dealer to reflash it and make it work. But again, usually replacement is the final repair.

Let me know if you have other questions.
