The oxygen sensors are all on the exhaust system. There should be one on each side of the engine (front and rear, that is) and one more downstream sensor just a little past the catalytic converter, but before the muffler. Changing them is simple, really. You will need either a 7/8' wrench or a ratchet with a oxygen sensor socket (also 7/8'). Just take one out and put the new one in.
