I think Ford put out a recall on them earlier. Not 100% sure. But either way it's a quick fix.. just swap it out. Part of emissions system so has to be warrantied for 7 years I believe.
Aren't you deleted though? ?
I can't find and info on that code. There is a campaign for the nox module reprogram. It's a 12B33. Trucks built before Oct 11 2011. Although that code was not listed in it.
Its just tuned DPF present as of now. I cleared it again and it went away. When it does it again ill tke it to the shop. Never deleted it alwys dpf present.
