Where is the oxygen sensor on 2002 Dodge Grand Caravan located?

The location of the oxygen sensor(s) on a 2002 Dodge Grand Caravan depends on the engine. There's typically one upstream (before the catalytic converter) and one downstream (after the catalytic converter). They're usually threaded into the exhaust manifold or the exhaust pipe itself.

To find them, you'll need to:

1. Consult your vehicle's repair manual: This is the best resource. It will have diagrams showing the exact location for your specific engine (3.3L, 3.8L, etc.).

2. Look near the exhaust manifold: The upstream sensor is usually located near the exhaust manifold, close to where the exhaust gases exit the engine.

3. Look downstream of the catalytic converter: The downstream sensor is located further down the exhaust system, after the catalytic converter.

4. Look for a wire harness: The oxygen sensor will have a wire harness connected to it. Follow the harness to locate the sensor.

Without knowing your specific engine size, it's impossible to give a precise location. Getting under the vehicle and looking carefully along the exhaust system with the help of a repair manual is your best bet. Be cautious when working under the vehicle, and ensure it's properly supported.
