There's a *high probability* of having only one oxygen sensor on this vehicle's configuration. However, some later-year models or variations might have two. Without seeing the specific emissions system diagram for that exact year/model/engine combo, we can't be 100% certain.
To locate it:
* Consult your owner's manual: The best resource, if you have it. It should have a diagram of the emission system.
* Look under the vehicle: The sensor will be a threaded device with a single wire connected to it and is usually near the exhaust manifold/catalytic converter junction. It will often have a protective heat shield around it. Be careful when looking as the exhaust system will be hot.
* Check a repair manual: A Chilton's or Haynes manual for your specific vehicle will have detailed diagrams and locations.
Remember, the exhaust system gets extremely hot. Let it cool completely before attempting to work on it. Wear appropriate safety gear.
