Is it time to replace your Mazda Millenia Oxygen Sensor? If your current oxygen sensor has been in your car for 60,000 miles or more, you should replace it to keep your engine running its best. Your O2 sensor takes a lot of punishment inside your exhaust. When you are driving your car regularly it tests millions of gallons of exhaust every week.

This sensor plays a very important part in keeping your Millenia running cleanly and efficiently. If you leave it in too long without replacing it, your catalytic converter has to work much harder and will wear out much more quickly.

The oxygen sensor’s job is to make sure that your engine’s air to gasoline ratio stays exactly what it should be. When your engine goes through exactly 14.7 times as much air as it does gas, it is working at peak efficiency. The O2 sensor uses a small electric charge and a voltage detector to send a message to your computer and let it know what your air to gas consumption ratio is. Your computer then automatically adjusts the fuel injection to get the gas and air in the right proportion. If your engine is running rich and not getting enough air, your catalytic converter has a more difficult time cleaning your exhaust and will wear out a lot faster. This will also produce unacceptable levels of emissions and could keep you from passing emissions tests. If your engine is running lean and not getting enough gas, it will definitely cut down on your power and gas mileage.So if you know you need a new O2 sensor or you’ve gone 60,000 miles with the one in your exhaust now, order a new Mazda Millenia Oxygen Sensor from our website or toll-free number today!
