Oxygen sensors are usually located on the exhaust just after the exhaust manifold and just ahead of the catalytic converter Depending on model as some have one sensor, some have two and some have four of them, I would look just before and just after the catalytic converter. The sensor reads oxygen content and reports back to the Powertrain control module (computer) the one before and the one after have a different reading as the converter changes the content. The PCM evauluates and change the fuel air mixure to correct.

oxygen sensors are located just forward of your engine. In front of the engine is the catalytic converter. At the top at the bottom are your oxygen sensors.
