Hello mustang people my v6 2012 mustang is giving me a check engine code of p2247 o2 sensor reference voltage circuit open bank 2 sensor 1... I just installed off road h pipe and got the tune and everything.. Today I went under the car and unplugged the drivers side and took out the o2 sensor put it back in and still getting the code.. I was assuming it was the passenger side o2 sensor because it was an extremely tight fit so I was thinking maybe the wires shorted out or something. But I called around and i learned that bank 2 is the drivers side so I don't know what to do now :-( is bank 2 even drivers side?
