Elusive P2002 Code
I finally made my return into the diesel world after 10 years. The rig, a 2008 F250 FX4 Crew, LWB w/ 150K on the clock. Its a huge truck and was not my first choice but due to the mileage and year limitations on financing, its what I ended up with. For all intents and purposes of this post, the truck is assumed to be stock. I don't see any aftermarket pieces on it and I didn't receive any tuner with it.
I have been driving the truck about a week and a half have noticed a few things that make it much different than my 94 IDI Turbo I had. First and foremost, I thought with almost 20 years newer technology, that the fuel mileage would be better. Not so much the case. Going by the "lie-o-meter", as its so passionately referred to here, I am averaging about 10.5MPG unloaded and driving through the city like a grandma. Real world calculating has me around 10MPG. Now, this may be related to some of the other things I am about to say but if not, that is some insanely terrible mileage. My IDI got about 14MPG around town. Just never got better on the interstate.
With that being said, I ran into an issue the other day. The truck went into, what I guess is, regen mode (Cleaning Exhaust Filter). It blew some hefty clouds of blue smoke on take off which freaked me out a little. It did this for a few drive cycles because I was unaware that I should leave it running to complete. Anyhow, shortly after that cycle, the CEL came on with the P2002 code. DPF below threshold. After researching the heck out of it, I bought a more capable scanner, cleared the code, and it almost immediately came back. Cleared again and drove. It is now in the pending codes and will hard set on the next cycle. I parked the truck because 10.5MPG @ 3.88/gallon is a little hard to stomach at the moment.
Everything I read points to aftermarket intakes being the culprit. I do not have an aftermarket intake. I am not sure what kind of filter is in there as I have not looked yet. So to all you diesel gods out there, what is the most likely issue that causes this code on a STOCK truck? I am pricing a DPF delete system, but I am not sure if this will solve the problem with the mileage too. Is it really that bad?
