(b1). also my truck is stock! any body have this code before? is the truck drivable, i was heading out of town today.

Thanks for any help

Have never seen it. I'd call the place you bought it from and ask to speak with your Diesel Mech. These trucks are picky with the DPF's and EGR's on 'em.

Before u do any work to the truck, take it to a ford dealer....have them pull the code. Tell them its emissions related! Anything emissions related should be covered under your federal emissions warranty.

Does not matter if u are out of factory warranty.

until you alter the factory emissions parameters
