I have a 95 Grand Cherokee and would like to know where the O2 sensor is located on my vehicle. Thanks.

Depends on what one you are after. Most all vehicles have upstream (before cat converter) and downstream (post cat converter). Usually each bank will have a sensor in the exhaust manifold if it is a v8, and one after the cat. What engine do you have and which one are you after?

For a 4.0, it will be.. drivers side, under intake manifold, just below the collector on your exhaust manifold.... The leads that run to the O2 sensor will be same side and feed in between the front of the intake manifold and the power steering pump.
If you crawl under the vehicle on the drivers side, it will be very easy to see.

I have the V8 engine.
