Yes I got this today as well. I had it a few weeks ago and they replaced the turbo sensor. The code I got today is P0299 which I think is the same code that I got a few weeks ago. No harm has been done to the jeep... I believe the turbo is shut off till after you get the code cleared. Just guessing there
Service Electronic Throttle Control
I was driving home from northern Michigan today and about an hour into the three hour trip I heard a ding and the EVIC showed a lighting bolt with a warning that said Service Electronic Throttle Control and the MIL came on as well. The Jeep seemed to lose about 50% power and struggled climbing even the shallowest grades. I stopped at an auto parts store and sprayed down the MAP with throttle body cleaner and that didn't seem to help. We limped the two (sketchy) hours home and will be calling the dealer tomorrow.
Has anyone ever experienced this before? I lost all boost, but it would shift just fine, cruise control worked, coolant temp was fine, transmission never got above 197 and it was 85+ degrees out. Thoughts? Prayers?

I’m dealing with it right now on our 14. Fine around town but on the highway every time I’m getting a P0234 and a U1424. I’m glad I have a scan gauge so I can clear the codes while driving and get power back (until it pops back up). I replaced the MAP sensor but it didn’t help. I’m dropping it off at the dealer today. It feels like a wastegate issue as the boost doesn’t drop off quickly now.
Hopefully the aem warranty covers it.

Have you checked intercooler piping ? Maybe a hose has just dislodged. The plastic intake muffler has been known to separate as well they will both cause boost problems and throw engine codes.
Opps just read again... it is over boost problem possibly the actuator

Dropped mine off today and they are telling me it’s the egr cooler....doesn’t make sense since I have GDE and it’s not opening the egr anyways. We will see. They say it’s covered under the aem warranty, but of course they don’t know when they will have it. I’m stuck in a 2016 ram in the meantime (yes a 2016, but it’s better than no loaner).
How do you have the AEM and GDE?

Had GDE pre AEM and got a reflash update after the AEM a month or so before they stopped selling it.
I won’t be surprised if it gets flashed over by the dealer though. Id rather have the warranty at this point since I’m at 129k and only need it to last another year or two anyway.

The service throttle means it's in torque reduction mode "limp mode" to save the engine from overheating, basically because it has some type of engine/emissions fault.I was driving home from northern Michigan today and about an hour into the three hour trip I heard a ding and the EVIC showed a lighting bolt with a warning that said Service Electronic Throttle Control and the MIL came on as well.

Which code does it have?
P0299 is the only code that came up. Turbo under boost. There was a loose hose clamp on the turbo outlet pipe and there was some sludge that spewed out a bit. I tightened it and disconnected the battery for a half hour. Code popped up again as soon as I started it again.The service throttle means it's in torque reduction mode "limp mode" to save the engine from overheating, basically because it has some type of engine/emissions fault.

I'm under the AEM warranty so we'll see what the dealer says when I bring it in tomorrow
Check the oil separator... That's what the dealer said mine is

So I heard back from the dealer today and they said they need to replace the intake manifold as well as something with the fuel system. I'll update you guys on everything when I get it back on Friday
So they replaced the oil separator and the light still came on ... Getting nervous now.
Just got a note from the dealer. Turbo is shot .... This better be cover under aem warranty ....
From the aem warranty doc ....
The turbocharger system including all related hoses and pipes, all sensors and actuators

I got the Jeep back Friday and all seems to be back to normal. They replaced the intake manifold, fuel supply tube and turbo water feed tube. They said the code was due to all of the soot build up in the manifold. I wish GDE was still selling their hot tune that turned off the EGR
I've had this a dozen times after the first AEM. Mine comes back with P0193 code Fuel Rail pressure Sensor Circuit High. Of course the sensor was not covered under warranty. So I went to a local diesel mechanic and had it replaced for $300 vis the $850 the dealer wanted. Worked fine for 3 months. Has been back many times. Talked to the dealer asked doesn't this mean the covered fuel rail is the problem. "No"
So I clear the code with OBD Fusion app on my iPhone and stop and restart the car (once or twice) and the limp mode goes away and the dashboard light will turn off after 100 miles or so. Love this car and for a 4x4 to get 26-28 highway mpg (used to be 30) has been wonderful for 80k. But this has happened when my wife has been driving, so the Jeep is probably on it's way out. I haven't had the latest AEM done, but don't see anyone on here that has had the same issue and don't want to start another list of problems with the latest.

I'm with you man, good thing my wife "gets" to drive the JLUS and I take the JGC or else we would be looking for a gladiator.

So an update on mine. Picked it up today after sitting at the dealer for 31 days waiting on an egr cooler and new manifold. I made it a whole 4 miles down the road before the same errors popped up again. Turned rights around and picked my loaner back up. Hopefully they can figure it out and have it back in less than a month this time.
update they are now going to replace the DPF and sensors this time around.

Guess if they through enough parts at it they will finally figure it out. SAD 😕
Ive had that happen twice, all within a month of each other. It was the DPF at 100%, and had to be forced regen'd by the dealer
