I see the generic answer for the P0219 but on my 2012 Ford I got P219B.

Question

2012 Ford F150 5.0 liter running with less than 500 miles on the engine and with a CNG system installed. Got a code P219B. I saw the P0219 generic code answer but this one was P219B, I\'m guessing the B was in regards to bank 2. I have had this before and I asked Ford but they were no help. The truck runs fine otherwise.

Answer 1

I'm getting the same on my 2011 F150 Raptor, CAI installed as well as headers, high flow cats, and Roush exhaust. I'm also getting 2098s and 2097s. I know this has to do with the high flow cats and the O2 sensor parameters, and I'm told that a tune fixes it. Is the 219B gonna be a big problem though until I get it tuned? My meter's readin it as Bank 2 air-fuel ratio imbalance. Truck runs fine, kinda rough when I start it cold though.
