Message...."Service Electronic Throttle Control"....No codes & SFT

[EcoLeesiel]

We came to the conclusion that tuners are writing out that DTC code for EGT as it didn't appear on my scanning tool for my SFT tune, HP Tuners, or MRTune when installed on my truck. Throw the stock tune in and it's there among the 20 plus other codes and we missed it as did the 3 other mechanics who "worked" on my truck. A shop in Ontario reached out to me through FB as they had the identical scenario on a freshly tuned Ecodiesel and spent countless hours trying to solve. Ended up whoever did the tune unplugged EGT #1 and once plugged in voila problem solved. Hope this helps... cheers

Hopefully you’re still active. I’m also in Ontario. Anyway you have that shop info? (Message me if possible) I just did MR tuning (stage 2) last week full delete with exhaust. Cut all sensors from downpipe on. Didn’t touch egt#1 sensor. Since the tune deactivates all the other sensors and they were near impossible to take off I just cut them all off. And then tonight. service throttle message came on, only 200 km after doing the tuning no engine light no codes so I’m wondering if I’m having the same issue as you

Did you figure out what was happening to yours?

My fix was a bad #1 EGT sensor just after turbo.....new sensor and truck has been good as new. My truck is a full stage 2 delete with a an HP Tuners tune from Chris Munroe at E.O.C

What is sensor attached to? If you have full delete? I have EOC stage 2 and just had same error message Getting code reader today...
Yesterday truck started normally..but today again error message and run for minuite then stop...

So this happened this week...

Last friday I started the truck and was leaving the parking lot when all of a sudden the message center said "Service electronic Throttle Control". It seemed to be running fine and I was able to get home. I scanned the computer with my Autel MaxiCOM tablet scanner and found no hidden codes present. So with nothing to erase I went to my service menu and did a recalibration of the throttle valve. Message still there.... so I decided to try and drive it again. It started fine but when I tried to drive it was in limp mode and couldn't get over 40 along with shuddering under load and the intake sounded like a pressure cooker as it was sucking the air into the engine. Stumped and under warranty I took it to the dealership. They "reprogrammed" it to fix it Monday saying it was an old program. I went to pick it up at the end of the day and it was shuddering WAY worse under load. It eventually went away by the end of the day. I noticed too that my MPG went from 22 to 17!! WAY TO RICH! The next morning I started driving it and once again before I left the neighborhood the "Service Electronic Throttle Control" message. So back to the dealership it went and they paid for the tow this time since it was the same issue unresolved.

They called me this afternoon to talk to me about the emissions being turned off. I told them that I put a SFT Tune on it because there is no fix insight for the EGR issues that these trucks have and I'm not about to have a $30k truck go up in smoke or continually break due to the excessive soot. They responded by saying that they believe that my problem is the SFT tune, but they are going to have another higher up tech check it out for a wiring issue. I told them that there have been no other documented cases supporting their belief so I don't feel that they can prove it, but they might just have to flash it back to the stock tune to see if that cures the problem. They are trying to work with me on it, but the top dogs in the Chrysler tech are no longer willing to help them because I put the SFT Tune on the truck.

Service Electronic Throttle is a generic code for these trucks. A very common issue is the connection with cabling underneath the truck below the driver’s seat. It is along the rail. Disconnect your battery, open up that connection and put dialectic grease on the connections. Another issue is loose turbo boots. Also, make sure your MAF is clean. Just some simple stuff to check.
