Greetings - I have a '12 Regal 2.0 turbo engine light code indicates bank 1 sensor 2 location which is supposed to be after the cat. I located sensor 1 (pre-cat), the center sensor (in-cat), but I cannot physically find sensor 2 after the cat. Does anyone have diagram of all O2 sensor locations. Thanks - Frank

Thanks for your help. That's what I was thinking bc I couldn't find a third. Problem is the "exact fit" NTK 21067 that I purchased has a male connector the sensor in the cat requires a female connector!
