To be certain, you should:
* Consult your vehicle's repair manual: This is the most reliable source of information for the exact location.
* Look at a wiring diagram: This can help you trace the oxygen sensor wiring back to its location.
* Visually inspect the exhaust manifold: The sensor will be a threaded metal cylinder, usually near the collector of the exhaust manifold.
Caution: The exhaust manifold and components near it get extremely hot. Allow the engine to cool completely before attempting to locate the sensor.
