Anyone out there know what tha t code means on a 2011 3500? My signature truck. I am guessing that is means my air cleaner needs replacing. I just chnged the oil today. Thanks in advance... .

Thanks' just found that one myself. I have been having a P2271 code which a dealer in Missouri cleaned a sensor in the DPF. But it thru the code again about 2000 miles later. Now it thru this code that I asked about. I will take the truck to a dealer in NH and have them look at it. We are heading south annd west back towards Kansas.

Thanks again.
