I found it, it isnt loose but driving across country no issues suddenly this morning all of this happened

- service electronic stability
- electronic throttle control (flashing)
- exhaust system service required
See dealer
- now in limp mode

yesterday one of the TPMS sensors stopped working passenger rear

this is first trip in new off the lot gladiator. 6000 miles in odometer, flawless until this morning.

WTF?





Reference this post. Where is that located?

Diesel:




Gas:




Keep in mind, when Jeep changed the PCM model the connections went from the side to top of the PCM.

There is a harness that can get overheated, Routed too close to a heat source.
Not sure where it is or the fix, but I believe it causes some of your symptoms.

Grounds?

Every thing tight?

Check all the fuses, some times they are loose, Just press them down make sure they are all seated.

Did that first thing, no changes.

i can get up to speed on flat ground but struggling on hills. What are the chances I can get 700 miles like this?

x2, the wire harness overheating from resting on the EGR fitting near the top of the DPF as mentioned in the following thread can cause the issues you're seeing: https://www.jeepgladiatorforum.com/...steering-and-other-intermittent-faults.46673/

Even with repositioning the harness, you will still need to use a scan tool to clear the fault code that's currently got you in limp mode. Not sure I'd want to try to leave it in limp mode for 700 miles, but you should be fine to drive it as is for a while to get to where you can clear the code.

Where are you currently located? Any local shops or parts stores open that might be able to at least pull codes to verify what's kicking out (maybe even clear them)?

Same thing happened to me last summer driving across Texas. Cleared codes with my Taser and rolled on. Stop at an O'Reilly and buy a scanner. Document the codes and take pics of everything before clearing codes.

Update

weirdness. Stopped at auto parts place scanned and cleared, full power restored
Code: DPF soot buildup

only 6K miles, how can dpf be clogged already?

Active regen is turned off
Passive turned on

why am I never seeing the regen notification come on like others have?

Hey Max I may have missed it but what year is your JT? Reason I’m asking the 23’s are not routed the same as previous years I also have a 21 JLUD that was routed close by and I fixed it a preventive Measure. My vehicle is currently sitting in the Shop with this same exact problem. https://www.jeepgladiatorforum.com/forum/threads/jtrd-broken-in-tx.82550/page-3#post-1360796. I was able to drive it from Dallas back to ABQ. My DPF was not full but I was getting the warning this was confirmed at the dealership. They are replacing the DPF sensor said it was bad. By chance on your trip would you feel your vehicle get really hot for a few mins every couple hundred miles?
