ive got limp mode with no codes the only thing i can think off iss the dpf has been off with no prob and the quad with no codes now to night we got lots of rain the only thing i can think of is the sensor wires (conections) got wet there zip tied up but do u think being wet would affect them

 

I go into limp mode on the highway sometimes with no codes either. I never drive the truck hard but sometimes when the truck shifts from 6 to 5 or 4 to pass or go around someone it does it.

I have not tried to take the PPE out to see if it will still do it.

 

well mines doin it constantly evenidling, it needs and oil change can them oil changy magiger sensor thing make it go into limp mode

 

I am not sure, I have changed my filter 3 times with just over 15k on it so it would not seem like that would be the cause.

 

Is it limping the engine or tranny? Sounds like your getting a "tie-up". Change your filter first and see if it improves.

 

i guess the engine i can lear it and somtimes it will take 5 min to come back on and some time 30 sec, it fell like it just wont run like it would yesterday i thought fuel filter but (already went through that ) but no codes maybe ill get the wife to get both changed 2morrow

 

I usually just pull over, turn the truck off for 30 seconds and then it runs like normal. Now that I am thinking about it, mine did it before I got my PPE put on and I did that at around 1,200 miles.

I may not be tuner related.

 

mines prob driver related wife drives it with no problems but wen i do somthing always happens , it just makes me mad no code is through i gues ill just hold it to the floor wile keep clearin it and melt it down , i guess i might have to put the dpf back on and take it in, one thing also it used to not smoke with dpf but right before i took it off it smoke quite a bit with it on it might be broke too

 

If it limits you to 2000 RPM's its an engine limp. If it downshifts and locks into 3rd gear its a tranny limp. Its not unusual for it not to throw a code when you're running programmers or anything that can defeat what the ECM see's.

 

engine limp then i ve already had egr prob and miilions of times my dpf has cloged , i just hope it aint nothin real bad , but i guess you gotta pay to play exspecially if u got a new engine with a new product hackin things off and knw body realy knows if it really works or not yet
