P0 2002 and 0000 codes

[Trouble maker]

Were getting dumped on with snow and gave a buddy a hand on his farm ended up plowing through 4 feet of snow (seriously it was coming over my hood.)

About 10 mins worth of driving after that my check air filter light came on. Ended up being completely packed with snow. I brushed as much off as I could then re installed. On my ride home I got a P0 2002 code. I cleared that since I thought it was filter related, then I got a P0 0000 code. WTH is that?

I checked on the 2002 code and it was about the dpf but didn't find much more info. Truck is completely stock.

The air filter is likely causing the 2002 - check your other thread I posted more info there.
