2008 6.4 check engine light came on yesterday while driving. i pulled into Autozone and let then check it. Says P2002, they didn't know what it ment. I do know know what it is. My question is that while looking to se what this code meant everytime I saw another person with that code they had installed an aftermarket intake. Mine is fully stock. So any idea on what could cause this? And do i need to take it to the dealer, or will it clear? thanks for the help

Checked around and came up with this

Code description= This error occurs if an expected pressure drop through the DPF is lower than the specified value following a regeneration cycle based on the concept of normalized pressure differential.
Did you check your MAF sensor and wires connected to your intake? I would just check that, check your filter for any restrictions and if everything checks out and you have cleared the code then I would just drive it.
If it comes back then since it is under warranty take it in.
