Update on the gladiator eco diesel. Pulling the little nucamp 400 back up the turnpike from lower Florida. Wasn’t paying attention and started creeping up on 80 mph. All of a sudden, Shazam, limp mode.
Truck didn’t run hot, even though it was 90 something degrees outside.
Oil temp 240+
Limped it of the turn pike to some shade. Hook the little pocket scanner. Let it cool down a little, reset it and made it home.
Should I be concerned or slow down?
Thanks guys

Slower is probably going to be your friend when towing. I’d suggest an oil change and inspection if the oil got super hot. That can do weird things to the oil properties. Is it confirmed that oil temp is what caused the limp mode?

I don’t know if the oil temp has anything to do with it. According to google. Something with the turbo caused the code. I pulled another 300 miles with no problems

Got a lot of stuff on here about this. Has anyone really know what would fix this

 

[FC1]

Will a full delete fix it

Probably not.

I tow 3500lb cargo trailer and always drive to keep my oil temps below 240, I keep an eye on it close when it hits 230. I usually tow around 65-68.

I was under the impression oil temps need to get into the 260s before it'll trigger a derate. I've never experienced one myself but I can tell you I saw as high as 250 for short periods on steep grades on my last trip, and that'd usually be with sustained EGTs creeping up on 1400. That's when I'd start pulling back on the throttle. Low-mid 240s sometimes sustained for a while on longer grades and I just let it roll to see if it'd trigger something. Never did.

This is deleted and not pulling anything, just scooting along on 40s at 75-80 mph with a very non-aerodynamic rig.

I'm not sure oil temp was your issue. Maybe somebody can confirm if it'll derate due to EGTs. Seems logical to me that would more likely be the culprit if it threw a turbo related code. It might be a marginal difference but it does seem like the turbo should be able to shed heat easier without having to push the exhaust through a bunch of resistant heat-soaked components on the way out.

80 while pulling a trailer in summer heat is asking a lot, regardless.

I doubt you have anything to worry about. The engine has these protections built in for a reason.
