I have stock exhaust with muffler delete. i had the code once about a month after I bought the truck, cleared the code and it hasn't reappeared since. From what I have read it is a pretty common code...just means that at some point the boost was not within the set parameters the computer is looking for. It could happen for just a fraction of time to throw code.
Can Be caused by a bad or sticking turbo but not always. Kind of a phantom code for these trucks.
Not 100% sure but I beleive this code is thrown for both underboost and overboost conditions?......correct me if I am wrong. I don't think there is an actual code for overboost, it uses the same code number if that occurs.
I got the code while towing my work trailer with the cruise set, going up a hill, it was lightly raining and the truck downshifted, spun tires when it down shifted and reved real quick- i saw the factory boost gauge actually spike into the red zone for a moment! Then CEL came on- I thought I toasted something but it ran just fine so I cleared the code and it hasn't come back since.
