The O2 sensor measures the amount of oxygen in the exhaust. I may be corrected on this, but assume that any excess oxygen in the exhaust represents oxygen that could have been use in the combustion process. The engine will then alter the air/fuel mixture (timing too?) to the point where there is just miniscule amount of oxygen.
I just ordered an O2 sensor for the wife's Millenia, that thing has four sensors. One in each V-6 exhaust bank, one before the cat, one after. Local auto-part stores wanted close to $200 (or more) for a replacement. I found an universal model (you have to splice the wires instead of direct plug-in) at http://www.oxygensensors.com for a fraction of local prices.
I see where they have universal (made by Walker) for the SAAB 2.3 for $60. It says one sensor before the cat, one after.
I'm not sure what year your car, how many miles, but I'd consider just replacing both.
I realize this is getting long, but my 1991 Prelude had two sensors in the exhaust manifold, one per pair of cylinders. I assumed this allowed them to sample the exhaust from each cylinder, adjust accordingly.
