Good day y'all
I have a 2008 G5 2.2L. Fooling around with some other issues I found the PCM case is a bad ground. From the battery stud on the fuse panel to the frame of the TCM is a good 12VDC, but to the PCM is about 4VDC. I've read a lot on the TCM loosing a good ground, but does the PCM loose it's ground? I have no issues with the car running, misfires, codes, etc.
