So I get this error ONLY with the doors off. I got my JLUR in April of 2018. The 2nd summer every time I started my Jeep without doors I would get the "Service Electronic Throttle" error. Only for a split second. The dealer could never see the code and basically said it can't be fixed.

This year (my 3rd summer) it has only flashed twice with doors off, and at random times. However I do get the "Vehicle not in park" message every 5 minutes with my doors off.

Does your car ever go into limp mode? That happened to mine when I got the error. Couldn't rev the engine above 1500-2000rpm. That was the scariest part. Yesterday I pushed all the fuses down and then the next time I started the car, the check engine light went off, so it's no longer showing that there was any issue. So now it's working fine and I'm sure when I take it in the dealer is going to say there are no issues. Not sure what to do now.

Update...ended up being a bad “ECS Vacuum Hose”. It took the dealership a while to get the replacement hose kit but all seems well with the Jeep.
Does anyone have the part # for the vac hose(s) in question?

I continue to get ESC and ESS lights only after prolonged climbs at altitude (10k+) and as soon as I start down the other side.

My theory is that the engine is warm, possibly causing any hose in the engine bay to loosen/soften, and something about a high altitude slog combined w a sudden descent throws off vac readings.

I, thankfully, do not get any THROTTLE errors and thus no limp mode. It's actually NEVER affected driveability but it kinda makes me nervous

I clear the code with my tazer jl. Problem fixed for the last 24hrs.... fingers crossed will remain this way. I think I might sell this Jeep.

My 2020 Wrangler with 10k miles started doing this off and on a few weeks ago. It's dangerous. Seems like it started maybe after taking doors off once and putting them back on. Not sure but it also seems like when I top off the tank this happens. Not sure if either have anything to do with it. Might just be coincidences.

Edited to say... Here's the pattern. If I start the Jeep and drive for any amount of time straight through I don't have any problem. It could be 20miles or 200 miles it doesn't matter. But If I drive for a while and stop and shut the Jeep off, then go to restart it, the "service electronic throttle body" light comes on and the Jeep runs like crap, stalls etc. If the stop I'm making takes a long time (like driving to a restraunt and staying for an hour) it seems like either the Jeep cools off, or something resets itself and the Jeep will start and run fine. It's the short stops that make this happen.

Hey there, I would not hesitate to take this in and get a service trail started on it. Also, check out your state's lemon laws. We have had ours at the dealership for 3 months now trying to get this taken care of. Long story short, our less than one year old Wrangler with under 4k miles is a lemon. It's so sad! we love that thing and still plan to get another one. It's like an addiction.
Good luck!

I got the service throttle warning while driving from Denver to copper mountain. I felt no loss of power or anything, just sudden warnings. When I got home I was pulling up my driveway slowly and felt the engine drop rpm and I had to push the pedal harder to get to the garage. Next day no warnings or issues. I have to drive to California next week so it’s going to be a stressful drive.

It started for me when the doors came off too. It only comes on when the doors are off, and I can';t recreate the problem. Even under warranty the dealer wouldn't do anything about it. Said no codes and if I can't recreate it they can't fix.
