    There is no fuse on an O2 sensor that I am aware of. Did you clear the old codes first? The check engine light should have gone out and then came back on after the car warmed up if a problem still existed. Some codes will not clear even if the problem is fixed unless it's erased. Also depending on the car there may be four or five O2 sensors. Since you listed a bank 1 sensor 1 and a bank 2 sensor 2 that tells me there are at least four O2 sensors on that car. Please add more details as to make model and year please.

    You are starting at the wrong place.

    You have new O2 sensors already based on who's advice? AutoZone? They pull a code, give you a printout and pretend they are mechanics.

    Granted they can be useful but their 50 dollar machine is no substitute for a mechanic with years of experience and 20 thousand dollars of tools.

    You have already ignored all diagnostic procedures and flowcharts.

    Take it to a mechanic and ask him to charge you for diagnosis only if you are bent on fixing it yourself.

    The data you include is totally insufficient and I can't understand some of your grammar.

    It may not be your 02 sensor if it still showing oxygen sensor it could be a vacuum leak somewhere .

    Maybe it's an inline fuse link. Check the service manual.
