* 2.5L Iron Duke (4-cylinder): The O2 sensor is located in the exhaust manifold, typically on the passenger side (right side).
* 2.8L V6: The O2 sensor is usually located in the exhaust manifold or Y-pipe, again typically on the passenger side. However, the exact placement can vary slightly depending on the exhaust system configuration.
To be absolutely certain:
1. Consult your owner's manual: This is the best source of information for your specific vehicle.
2. Look under the car: Carefully examine the exhaust system for a threaded sensor with a single wire connector. This is the O2 sensor.
3. Check a repair manual: A Haynes or Chilton repair manual for your year and engine will show you a diagram with the sensor's location.
Remember to be cautious when working under the car. The exhaust system is hot when the engine has recently been running.
