Today, everyone agrees that we have to care about our environment and reduce the amount of pollution produced by vehicles. To encourage reduced emissions, the government has introduced tougher exhaust gas emission legislation. As a result, today modern vehicles are equipped with oxygen sensors that control the fuel and ignition systems to optimize vehicle performance in the areas of fuel economy and emissions. Generally, a vehicle is equipped with two oxygen sensors located before and after the catalytic converter. They check the amount of oxygen in the exhaust and send signals to the vehicle's on-board computer that regulates the air/fuel mixture and monitors catalytic converter function to ensure proper engine performance, optimum mileage, and low emission of air pollutants from the vehicle.
