When mine said ("SERVICE ELECTRONIC THROTTLE CONTROL SYSTEM"), This is what it meant for me. My intake air control valve was stuck closed. If I remember right this happened to me on the 470 south side of Denver. First few times it killed the truck I was able to restart it but eventually I couldn't restart the truck and had to be pulled backwards out of the way. Luckily I was able to get that gaskets and clean it and get back on the road.The message came and went away a few times in the week before that. Hope that helps.

If I wasn't DOT regulated I would have deleted long ago. We run fully legal though. Glad those pics helped. The egr is basically just pumping crap back into the engine. At least the way I've come to see it.

I am also having an intermittent issue with the service electronic throttle control light coming on. When in temps above 50 degrees it isn't an issue, but when in 30's or less, it comes on once and a while when stopped at a stoplight. I don't have my foot on both the brake and accelerator and not towing. I don't notice the truck running rough or anything either. The light goes out a couple seconds later. Now, with that said, the last couple of months i have experienced an increase in rpm's while towing, but after coming to a stop. This has happened once not long after towing a boat to storage and twice while towing my 5th wheel. Each time my rpm's would go from about 1500 to 2000 while i have my foot on the brake. I would tap the accelerator to try and get the r's to decrease but they would increase with each tap and hold steady. Recently, while stopped in heavy traffic, the rpm's went up to 3000. I put truck in park and shut it off. After a minute i restarted and it was fine.
I have since made it down to Florida and haven't had an issue with the light, or rpm's since. Don't know if this is the same problem you are having, but it seems to me the throttle control may need replaced? I have a 2013 Ram 2500. Anyone experience this before?

Following...

My ETC light and check engine light came on yesterday during my drive home from work. I live in Eastern Iowa and we had outside temps around 25F. Drove it last night a couple more times with no noticeable issues. The ETC light did go off on my way home late last night. This morning I got to leave for work and it would crank but not fire. "Stole" the wife's mini van to get to work today Later in the morning I had her go to the truck to see what it would do and it fired right up, no lights, no nothing, runs fine... I went home to take it to the shop and the only noticeable thing is it is hunting a little when it auto-idles. It fluctuates about 100RPM or so. Needless to say it is now at the shop being looked at.

I too feel a delete coming but need to get past the last 15 months of warranty...
