What good is a O2 sensor on a catalytic converter?

It monitors the air mix before and sometimes after the CC. If the engine is running at the correct fuel-air mixture there will be a certain amount, not too little, not too much oxygen there. It operates with the car computer in a closed-loop feedback system-- if there's too much oxygen, the computer adds more fuel (to burn with the extra oxygen).

If there's too little, it means there's too much fuel, so the computer cuts back on the fuel. It's the only way to get the fuel-air mixture just right-- constant checking and adjusting. In the very old days airplane and car engines could be outfitted with CO2 sensors, which did the same thing, only a bit less accurately.
