Already replaced the OPDA & had my shop do a sync & relearn. I was going to drive with the scanner hooked up to try & catch the blinking CEL, since it doesn’t leave a code.

My biggest worry is putting money into a new PCM in, after I found the plug tampered with. Hopefully, scanning while I’m driving will give me some kind of answer. I don’t want to keep throwing parts at it.
Call WranglerFix, search on the Forum and you will him. You likely have a fried PCM.

I spoke with Mark a few days ago. Looking at $950.00 for one, since I have a manual. The wiring harness is my concern...
The wiring harness is easy to test. If you have 5 volts at the sensor connection to ground then you are good power and ground side. If you are getting a known good signal at the PCM then the signal circuit is good. With both these circuits good then PCM is usually good.
Where the problem is in the aftermarket CPS and/or CKP sensors. What we have found is that the Mopar sensors all draw 8 mil/amps on the 5 volt power side while the aftermarket sensors do not. Seems the PCM is looking for that draw to verify the sensor is working correctly. Maybe some else can chime in on if they have seen the same.

Did you figure out your problem? Was it the ecm? Going through a similar experience with my 05
This sounds pretty close to my previous issues and I ended up doing a new PCM, none of those issues since! (06/manual)

I am leaning towards taking the step and buying a refurbished one. I already talked to Mark from wrangler fix. A local computer shop has mine now, hoping they can confirm it is bad before I order one. Thanks for sharing your thoughts.

Replaced my ecm with wranglerfix.com. So far so good! Mark was GREAT to work with.
