ECU Code P2270?

[Razzamatazz]

I tried searching around a bit, couldn't find much on it. Car randomly threw code P2270 today, after clearing the code with OFT I'm feeling a noticeable delay before acceleration begins. Like I press the gas and the engine waits a good solid second or two to respond beyond what it normally would. Sorry if this has been posted, I searched for the code but nothing came up.

Any thoughts?

did you just change headers ?


don't run any 02 spacers or 90 degree adapters if you have tune

REAR (second) 02 sensor stuck lean, sounds like damaged 02, damaged wiring or the 02 swinging in the breeze.


if your trying to fing meaning of codes google code plus Subaru eg in this case


google "P2270 Subaru"

Did that work? I bought my header used from a guy and had the 90 degree adapter and i got the stage 2+ tune... would getting rid of the adapter stop the cel from coming on and throwing that p2270 code?

Quite possible it will thow a stuck lean code for rear o2 if adapters and spacers used. With a tune no spacers or adapters needed both o2 sensors can go dirdct into header like stock.


Its also posible o2 sensor was damaged during install too mich force or dropping them can break them
