If you have noticed that your vehicle is running irregularly or that the engine sounds rough, there might be a problem with your oxygen sensor. When the mixture in your car (oxygen and fuel) is too lean or too rich, the engine becomes less efficient.
The O2 sensor (oxygen sensor) actions the quantity of oxygenpresent in the wear out gasoline. For appropriate combustion to occur, youneed 14.7 h of air per 1 gram of energy. The car has detectors tomeasure the amount of surroundings moving into the engine, and can consider apretty good guess at the amount of fuel going into the motor, soit can perform a quite good work of keeping the air to gas proportion aroundthe 14.7:1 mark. When the motor is awesome or under weightier load,thát's whát it will (it may actually 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 procedure. At that stage, ituses the O2 sensor to sense the quantity of air in the exhaust,and fine beat the quantity of gas heading in. If the U2 sensor will be notworking, it can't do this good tuning. Therefore long as it remains close to14.7:1, you're also ok. Nevertheless, if it begins wandering, you can haveproblems. As well rich and your cataIytic converter can ruin itself.Operating rich will discharge a great deal of unburned hydrocarbons (fuel)because there isn't sufficiently air to burn off them. Those will proceed intothe catalytic convérter, which will perform its best to obtain rid of thém,but the better job it does now there, the hotter it will obtain, and couldmelt. You'd likely have complications with any emissions tests. Plus,your gasoline usage will experience. On the flip aspect, if you move lean(not enough energy), your exhaust temps will rise (unless yougo method to slim, in which situation you may begin misfiring) and youmight obtain your cat (or your engine) too warm, with obviousconsequences. The extra heat and oxygen will allow the formation ofincreased levels of nitrous oxidés (another emission problem). Theonly great side to this will be that running lean can assist your fueleconomy (supposing everything else in your vehicle can deal with it). Soyes, a malfunctioning U2 sensor can damage your car.
