Anyone have any experience with this code? I notified dealer and they can't get me in for 2 weeks. Code reads turbo underboost but I had just recently had the recall fixed for the pm sensor and now my truck has done 2 Regens in 150 miles if that. Am I in danger of driving it another 1000 miles or more by the time it can get looked at? Dealer said it could be the dpf filter
 
What year and engine (ho/so) is your vehicle?
 
Ok the earlier HO trucks had that code pop up fairly often, there was a reflash available to change the reporting parameters which solved the essentially non existent problem. It sounds like if you are having more than normal amount of regens, you can have a underboost condition likely a leak in the intercooler system or turbo charger issue. Low boost=incomplete combustion=more soot=call for regen.

I also checked map sensor and cleaned it noticed a loose connector guess I knocked it loose changing my fuel filter I'll see if that helps but according to my boost pressure gauge it is still building boost like normal guess we will have to wait and see but thanks for the input
