Hello everyone, this is my first post here. I own a 2013 Ford Taurus SHO PP with an AFE intake and tune by torrie, just today when driving home from college the check engine light came on. When i got home i ran the code and the sct told me P-0151 and upon research i should replace the 02 sensor, along with the other sensor near it. I have no clue what part numbers i have to order and that's after a lot of research. Also, do i have to replace them in pairs or just the bank 2 sensor 1? Thanks for any help.
