Thread: dpf clean

I have an 07 diesel and today the dic gave me a message to clean the dpf. Can I do this myself or should GM do it? If I can do it myself what exactly am I looking for?07 Sierra Classic, 5.3L, 4X4, Crew Cab

I think that just means you need to drive it around at hwy speeds for a little while and let it regen..... Have you tried looking it up in your manual though?Joseph

That seems a little more serious now. Sounds like time for the stealership to step in. Is the truck under warranty?

I'm with Joeairforce, I thought the dpf was self cleaning. Also I've been told that you can't cut the dpf out, truck won't run after a few miles without it (reduced power). But I can't say for sure. Check the owners manual about servicing the dpf.

The system will regen on its own unless you stop the system from performing its clean up process by stopping the engine during a regen or the differential pressure sensor on the exhaust that measures exhaust back pressure failsROADMECHANIC9

well i took it in and the mechanic checked the 2 codes it had and only recommended changing the air filter. he reset the computer and figured i'd be good to go and have had no problems since.
