6.7L Cummins Forum

I have an 09 6.7 with a standard 6 speed. Driving around the mountains always ends with the engine light turning on. A couple days later after normal use the light goes away. I understand that low rpm is the cause for the light, but you can't run around with high rpm in the hills all the time. Is there anything that can be done so this doesn't happen .

Did you have the j35 new upgrade recall done? Look in the forum where it said another recall it will tell you all about it. Good luck.

Thank you. I haven't had the j35 done. I'll take care of that and post back.
