Where are the oxygen sensors located on a 1992 town car?

A 1992 Lincoln Town Car will have one or two oxygen sensors, depending on the engine. There's no single definitive location because different engines may have them in slightly different spots. However, they're almost always located in the exhaust system:

* Most likely location: Before and after the catalytic converter. If it has two, one will be upstream (before) the catalytic converter and one will be downstream (after). These are usually on the exhaust pipe itself, close to the catalytic converter but before the Y-pipe if present.

* Finding them: Look for a threaded sensor, typically about 1 inch in diameter, wired into the vehicle's electrical harness. They'll be in the exhaust system, likely in a relatively accessible location for replacement. You might need to get underneath the car to see them clearly. A shop manual for your specific year and engine would provide the most precise location.

To find the exact location for *your* 1992 Town Car:

1. Identify your engine: Knowing the engine size (e.g., 4.6L, 5.0L) will help you find a more specific diagram.

2. Consult a repair manual: A Haynes or Chilton repair manual for your vehicle will have diagrams showing the exact location of the oxygen sensor(s).

3. Use an online parts diagram: Many online auto parts stores (like AutoZone, Advance Auto Parts, etc.) let you select your vehicle's year, make, and model and view diagrams showing the location of parts. Search for "oxygen sensor" in their diagrams.

Remember to always disconnect the negative battery terminal before working near the oxygen sensors or any electrical components in your vehicle.
