Ive had an issue with this code now pushing a year now. Originally had the code. Put in a mopar TPS and aftermarket solenoids. The code went away for about a month then came back. It would stay on for a week or so then go off for a week or so. Now its just always on. If i clear it it will return immediately as soon as i turn the jeep on. It doesnt even let me drive before it puts on the CEL.

Last night did testing. Resistance from TCM to each solenoid was around 15.8 ohms and from the black plug under the hood through the TCM to the solenoids is showing 15 ohms. Im stumped at this point.
