    The sensor ‘sniffs’ the exhaust & measures the amount of oxygen still in the exhaust. If there is too much O2, then there’s not enough gas going into the engine. And if there’s too little O2, well, you can guess. It’s the best current way to get the right amount of gas into the engine, balancing power & pollution.

    it measures oxygen in the exhaust. there are 3 if it is a v-6. One for each cylinder bank and one common after the catalytic converter. If any are bad, the check engine light will be on (I think you have the problem now or you would not have asked) and if you do not replace it, your fuel economy will go down badly. If you continue to drive it, you may foul spark plugs from running a rich mixture and you could load up the catalytic converter and plug it (they are very expensive).

    the oxygen sensor mesures the level of unburned fuel in the exhaust. the power train control module (pcm) uses this information to adjust the fuel/air ratio to give optimal fuel economy/power/emissions.

    I think that car has 3,but not sure.

    a 02 sensor monitors the oxygen in the fuel and sends a signal back to the computer so it can adjust the mixture. you could have 2 of them.1 in the exhaust manifold and 1 in the cat.converter.
