The O2 sensors are located in the exhaust piping.
One (bank 1) is on the engine side of the Catalytic convertor.
Second (bank 2) is on the other side (exhaust end).
There are manufacturers that make universal fits that will go in either location. Be sure to specify the rear sensor when you go to the parts store.
It will look like this....
It threads right into the exhaust pipe.

ALL of your oxygen sensors are located i your exhaust system Your exhaust system starts at the exhaust manifold on the side of the engine and ends at the tail pipe by you back bumper. Your vehicle oxygen sensors are 4 of them there are two on each side of your exhaust the are actually screw into the exhaust they are like the nose of you engine to read how rich/lean the car is running. The are pretty simple to replace, they look kinda like spark plugs with wires attached to them the wires are usually colored white black and grey with plug connections on the end. To replace get a oxygen sensor socket and a ratchet and unscrew this socket can be bought at almost any auto parts place like auto-zone etc. Good luck and thanks for using FIX YA

SOURCE: location of oxygen sensor
I believe you may have three (3) O2 sensor, (2) of the sensor is on ether side of the exhaust down pipe and some times called up stream O2 sensor, the third O2 sensor know to some as the down stream O2 and is after the Catalytic converter.
The up stream O2 monitors the left and right side banks and sends signals to the ECM to make the adjustments to the injectors to keep the proper air/fuel ratio.
The down stream O2 monitors the catalytic converter and sends signal to the ECM if the catalytic converter has gone bad.
Good luck and hope this helps. If you get it scanned at Auto Zone, they should be able to let you know which O2 has gone bad so as to not change all three. You could always check the wire harness to the down stream O2 for corrosion. Keep me posted
