Bank 1 sensor 1, Cadi wanted way to much to change it and I disabled so I'm trying to change it myself. Would really use your insite.

Thank you

Bank one is the rear bank on this, if you go down over the rear cam cover about where the secondary air valve is, it threads into the top of the manifold. You will probably need a crowfoot, and possibly a universal extension. The sensor connector is clipped to the same bracket as the secondary air check valve.

A crowfoot is basically, an end wrench, made to go on the end of an extension, working from the side like a wrench, in a space suited for a socket. Here is a picture.
