2015 that has about 180k on it. I’ve had a GDE tune and been EGR, DPF, Cat, and DEF deleted for about 80k miles I think.
I was driving home 60% of the way through a 12 hour trip. Houston to Albuquerque. HOT HOT HOT and HOT again. Truck was running fine/normal until I crossed the TX/NM border and it threw the CEL, Throttle Control warning and Exhaust Service see dealer. Now I don‘t have a DPF or an EGR that can be plugged. So I’m trying to figure out what to look at before I dig in.
The only thing out of the norm with the truck is that night before last, I pulled over at a rest stop to catch a quick little 20 minute nap, and woke up 7 hours later when someone called me. No idea how it happened, but it did. And its east Texas so temp was still low 90s and high humidity so naturally I had left the truck running with the A/C running. But I stretched my legs, hopped back in and took off down the road and it drove fine for 8 hours before it gave me the codes, so maybe its unrelated.
Unfortunately, where I broke down is the middle of nowhere. I tried resetting my codes but my reader wouldn’t do it. Tried disconnecting battery and discharging things and still didn’t do it. Checked on a tow and it would have taken them 6 hours to get to me, then another 4-6 home and not sure how much my insurance would cover. So I said to hell with it and decided to drive it home in limp mode. I found a way to feather the throttle to get it to shift and even with absolutely zero boost I could get it up to 65mph on flat ground. Going up hills wouldn’t drop below 40 mph. Oil pressure and temps all stayed acceptable throughout this stressful, long and drawn out 5 hours in limp mode to get home.
So what parts should I be checking? I saw a recent post that mentioned the map sensor so that will be where I go first I guess. But then after that, I’m not sure what to dig into.
