Help!

[CanuckF350]

Hey guys! I need your help. My truck has not done a regen for 450kms(280miles). Today it threw a code P2002 Diesel Particulate Filter Efficiency Below Threshold. Truck seems to be running fine. Temps are normal, boost is normal. I have an AFE Stage 2 intake. Could the intake be throwing the code?

Thanks for any help you give.

I had the same problem, its the intake.

Anyother thoughts on why it has not done a regen for some time now?

Update
Well it finally did a regen. Now for the first time when mashing the peddle to the floor I get a nice roll of smoke. It has never done this before due to the DPF. Does this now mean that my filter is on the way out? Or was my last regen responsible for cleaning it out enough to get that tell-tale diesel sign of smoke out the pipe?

My '08 doesn't Regen that often either,and I'm glad because I can tell the difference in power. It did a regen one time when I was hauling a very heavy load of scrap metal for a friend and I could tell the difference.
I'm wondering why an intake would set a code for the exhaust filter though.

Air in air out differential.

I was told if it smokes with DPF on that it can have a crack it or its shot. Thats just what I was told.

I had an AFE II and got the same codes after every regen. When the dealership plugged in their computer it popped up as aftermarket equipment. I got a look from them that I didn't like and had them put the stock air box back on. Haven't had a code since. The AFE was the only non-stock part on the truck.
