Where is the O2 sensor on a 1998 Dodge Caravan?

The exact location of the O2 sensor(s) on a 1998 Dodge Caravan depends on the engine. There's usually one upstream (before the catalytic converter) and one downstream (after).

To find the location, you'll need to:

1. Identify your engine: Look for an engine code (like 3.0L, 3.3L, 3.8L) usually found on a sticker under the hood or in the owner's manual.

2. Consult a repair manual: A repair manual specific to your 1998 Dodge Caravan and engine will have diagrams showing the precise location of the O2 sensors. You can find these manuals online or at auto parts stores.

3. Use an online parts catalog: Websites like AutoZone, Advance Auto Parts, or Napa Auto Parts allow you to search by year, make, model, and engine. Entering your details and searching for "O2 sensor" will often show diagrams highlighting their location.

General areas to look:

The upstream sensor is typically located in the exhaust manifold or very close to it. The downstream sensor is usually located in the exhaust pipe after the catalytic converter. They're usually threaded into the exhaust system and have a wire harness connected to them.

Caution: Exhaust systems get extremely hot. Allow the engine to cool completely before attempting to locate or access the O2 sensor. Wear appropriate safety gear, including gloves.
