Where is O2 sensor located on 2002 dodge caravan?

The location of the O2 sensor(s) on a 2002 Dodge Caravan depends on the engine type. There's typically one upstream (before the catalytic converter) and one downstream (after the catalytic converter).

To find the exact location, you'll need to:

1. Determine your engine: Check your vehicle's paperwork or the sticker on the driver's side doorjamb to find out the exact engine size (e.g., 3.3L, 3.8L).

2. Consult a repair manual: A repair manual specific to your 2002 Dodge Caravan and engine will show you diagrams and precise locations of the O2 sensors. You can find these online (often as PDFs) or at auto parts stores.

3. Use a parts catalog: Online auto parts stores (like AutoZone, Advance Auto Parts, etc.) allow you to search by your vehicle's year, make, model, and engine. The parts diagrams often show sensor locations.

General locations (but these are NOT guaranteed for your specific Caravan):

* Upstream O2 sensor: Usually located in the exhaust manifold or very close to it.

* Downstream O2 sensor: Located in the exhaust pipe, after the catalytic converter.

Important Note: Working on your exhaust system involves high temperatures and potentially dangerous fumes. If you're not comfortable doing this yourself, it's best to take your vehicle to a qualified mechanic.
