2008 F250 Check Engine Light..
 

I was driving this morning and my check engine light came on. No where in town could look at it so I went by auto zone and they used their code reader and my truck showed a code of P2002. I couldn't find anything in this code in the computer. Any ideas what this could be? I put my new S&B intake on last night.

P2002 Diesel Particulate Filter Efficiency Below Threshold (Bank 1) that's what that code means, i have no clue other than that https://www.dieselbombers.com/ford-p...ble-codes.html here's the link,

Thanks. Hopefully someone knows if it's serious or not.

the particulate filter is stopping up

How many miles are on the truck?

37000 miles on the truck.

Do you idle it alot?

No I don't idle much at all other than routine city traffic.

Do you have a programmer on the truck? Do you frequently get on the throttle hard? Do you let it enter regen mode? Sounds like your particulate filter could be sooted up and the truck needs to regenerate the filter.

No programmer yet. I don't drive it hard. I do let it regen when necessary. The check engine light went off and the truck is running great. I think it was a false code caused by adding my aftermarket intake. Thanks for the helpful replies.
