Its funny how you would expect someone at a parts store to know which bank and sensor go where on a engine, but i have every guy at the parts store tell me a different answer, none that were what you said. One guy said that the bank 2 sensor one, was after the cat, the other said it was before, which is right, and the manager said it was the one facing the firewall, but none said it was the one by the radiator. heres my only question, i replaced the 02 sensor by the firewall within the last 1 1/2 years, and cant remember if the 02 sensor i replced(stock ford) had a white cable or not. see the pre cat sensor i replaced by the firewall has a red cable(bosch), while the one by the radiator has a white cable(im assuming its still stock). I know the harness is the same on the fronts, and the backs(after cat), but the color of the 02 sensor i got know is also red. SO, do the manufacturers make the same color wire for each sensor, or do i ignore all the bull#### and just replace the white 02 sensor i have up by the radiator? because that indeed is the bank 2 sensor 1. right?
too much confusionover a simple task, but i wanna be sure because the sensor by the firewall is a pain to change. thanks
