where is oxygen sensor on 02 monte

Bank 1 is probably the O2 sensor that's on your rear exhaust manifold. You're gonna need a 1" wrench (I believe it's 1"). And something to lube it up with probably.
The other O2 sensor is on your exhaust. Just look at the pipe under the car (around the cat, resonator) you can't miss it.

I would recommend using the special O2 socket to remove it (unless the location does not permit fitting one in). And hitting it a couple of times with PB Blaster (or your favorite penetrating spray) may not be a bad idea either.
When putting the new one on, if it does not already come with some anti-seize (I've seen some that do), I would dab a little on the threads.

The only reason I asked was because Advance told me that was what the code meant but it wasn't. Had I went with what they said before checking I would have bought it for nothing. A lot of the 2001-2002 models had bad cats that could be replaced free under a "special policy", mine was one of them. There's info here on the forum somewhere, that's how I found out about it. They extended the coverage to 8 years instead of 6 (I think), can't remember the mileage but more than 108,000 because that's what mine had. A sensor would be A LOT cheaper than a cat. Good luck.
