That's where my confusion is coming from. By definition P2270 Is Bank 1 Sensor 2, which refers to the post cat sensor.
I did check the tightness of everything down there. I an very usually very careful about putting the sensors in the same hole they came out of on the stock headers. I will double check the part #'s to make sure they didn't get switched.
