To change an oxygen sensor (o2 sensor) you just unplug it, and unscrew it from out of the exhaust pipe/manifold, and replace it. Also, if your up to it, the mechanics that do the repairs for the dealers, will do work like this on the side, for like fifty dollars, to change an oxygen sensor, all you have to do is ask them. Pull them to the side, and ask them. Because of the difficulty, there are really no instructions to do this because you just unplug and unscrew.
