The engine light is on and the code came back with an 02 sensor I replaced it, didn't work. The reason why I think this is the issue is because a friend of mine was having the same issue with his truck and his mechanic replaced it. My friends truck runs fine now, so before I replace it I would like to know how to test it. It looks to be a pain to do. Thank you
have the same problem?
