Persistent code 2fbc, what could it be?
Okay, so I was getting an occasional limp mode and code 2fbc. Searching doesn't really turn up too much for it but the few times it was mentioned it had to do with the fuel pumps. I replaced the lpfp first with an upgraded one, didn't fix it, so I just replaced the hpfp with the newest revision one. Code is still here!?! It won't go away, at all, even for a split second. When I clear the code it immediately comes back, even with the engine not running (ignition on, engine off). Makes me think it's something electrical, but I looked over the wiring and everything looked okay. Anyone else had this code? How did you fix it?
To recap: Limp mode Code 2fbc LPFP brand new HPFP brand new Code reappears even without starting the engine Thanks for any help, I'm lost here...  |

It’s not pumps, you have a communication issue. Anytime you have a hard code that won’t clear like this one, then you lost signal somewhere. The only communication is pwm driven , I’d be the ekp. Try and swap it out with a known good one, the na and turbo cars are all the same
