Best Answer: a bad 0-2 senors will cause a rich running condition on any car,the 0-2 sensor is what helps to make the system run leaner and cleaner so replacing the sensor may take care of that problem,that's what the 0-2 sensors job is is to rich-en or lean out the gas mixture for it,good luck and happy new years to you.
The U2 sensor (oxygen sensor) steps the amount of oxygenpresent in the exhaust system gas. For correct combustion to take place, youneed 14.7 grams of surroundings per 1 gram of energy. The vehicle has detectors tomeasure the quantity of atmosphere flowing into the engine, and can get apretty great think at the amount of energy going into the motor, soit can perform a fairly good work of keeping the atmosphere to fuel percentage aroundthe 14.7:1 tag. When the engine is awesome or under heavier load,thát's whát it will (it may also run wealthy, or even more fuel thanneeded, for extra power). As soon as the motor warms up, ánd you'récruising, it will go into closed-loop operation. At that point, ituses the O2 sensor to feeling the amount of oxygen in the exhaust,and fine beat the amount of energy going in. If the U2 sensor will be notworking, it can't perform this great tuning. So very long as it remains shut to14.7:1, you're also ok. However, if it starts wandering, you can haveproblems. Too rich and your cataIytic converter can demolish itself.Operating rich will release a lot of unburned hydrocarbons (gas)because there isn't sufficiently oxygen to burn off them. Those will move intothe catalytic convérter, which will do its best to obtain rid of thém,but the better work it will right now there, the hotter it will obtain, and couldmelt. You'd likely have difficulties with any emissions assessment. Plus,your gasoline mileage will experience. On the flip aspect, if you drift lean(not really enough gas), your exhaust temps will increase (unless yougo way to lean, in which situation you may begin misfiring) and youmight get your cat (or your motor) as well hot, with obviousconsequences. The extra warmth and air will allow the formation ofincreased amounts of nitrous oxidés (another emission issue). Theonly great aspect to this is that running low fat can help your fueleconomy (presuming everything else in your car can manage it). Soyes, a malfunctioning O2 sensor can harm your vehicle.
