Check Engine Light Code: P2BFB - Exhaust Actuator Valves

[Waterfowler41]

Starting this thread because I couldn't find any Raptor specific info on the topic. Intermittently over the last few months, I would get an error message when I hit the exhaust valve button saying "Exhaust mode not available" when I tried to bump the truck into Sport or Baja. Every so often this error message was coupled with a CEL at start up. If I saw the exhaust valve error on my screen, 99.9% of the time on the next start up, the CEL would be on throwing code P2BFB - Exhaust Flow Control Valve 'B' Control Performance meaning there's an issue with one of the exhaust valves. More specifically this code means the tailpipe valve is stuck in the open, closed, or in an unknown position so there's no feedback loop completion. (dealership gave me a ton of documentation on this)

Did some digging and found exhaust valve issues are common on some Mustangs but couldn't find anything for Raptors and specific this CEL code. Luckily the light came back on the other day and I was near my dealership so they scanned, made an appt, and gave me the diagnostic sheets that they will run through.

Anyways, opening this thread in case anyone else is seeing the same code. I will report back after my appt next week with what they did the resolve. I suspect they will be replacing the actuator.

TL/DR - Got error message saying exhaust mode not available, got CEL with code P2BFB, dealership digs in next week...more to come

Sounds like you have a bad valve. I've seen a couple of people on here that have had them replaced under warranty. Keep us posted.

I had the same thing about a month ago, code P2BFB, CEL and exhaust modes not changing. Tech found circuit CBK03 corroded and split about an inch from the connector. They ordered an new pigtail and repaired and it has been good since.

I had the same issue addressed at the end of 2022 and now my truck is making this noise and the Dealer said that Ford told them it is normal and there is nothing they can do.

I have had an error on exhaust in the past month as well, it recently happened twice more and finally popped this code. The previous event didn't pop a code, will need to take it in for warranty for this and HVAC not working well at 70+
