Hi Guys,
I am having issues with my truck past month. Almost every week my trucks both check engine lights are on and Regen light is on. I took it to Frieghtliner dealer few times and they fixed it at the times, but it’s coming back on almost every week. Has anyone faced issues like this? What should I do? Please help.
Check engine lights on and Truck won’t go over 55mph

Any codes?
-
It’s called a derate, keep driving and ignoring the check engine light, and you want go over 5mph.

Did you do a parked regen?
-
Your DPF is most likely getting clogged. You cannot ignore regens. It could be many things but don’t put it off. It will cost you much more if you do.

If its your truck and no warranty I'd advise "tuning" it

I would check sensor wires for breaks in them or if any of the outliner is rubbed off . The up and down stream sensors and also check to see what codes are being thrown. Just a matter of time until a complete derate.
