From the top, look at the exhaust manifold. There is a little device that's screwed into each exhaust manifold right about the location where all of the cylinders have come together. THAT's the oxygen sensors.

If you need to replace either, do them both at the same time. The other one is almost gone by the time you get the message on the first.

Just screw them out and put in the new ones. The replacement sensors MAY or MAY NOT have the same electrical plug so you may need to do a little surgery that way, but it's quite simple.
