To control unwanted and toxic emissions, which have increased tremendously in the past decades and threatened to destroy the environment, most of the vehicles produced after the 1980's have come with an oxygen sensor, a primary measurement device for the fuel control computer. Mounted in the car's exhaust pipe, the oxygen sensor's aim is to help the engine run as efficiently as possible by detecting the air and fuel mixture if it is too rich or too lean. It is a chemical generator device in which it constantly compares the oxygen inside the exhaust manifold and the air outside the engine. By feeding the data to the engine management computer, it generates the needed information of the voltage so that the computer can adjust the amount of the fuel entering the engine when mixture is not accurate thus, getting the best fuel economy, lowest emissions, and good power.

When your Chevy oxygen sensor fails to work, the computer can no longer determine properly the air/fuel mixture so that this leaves it guessing and will result to the engine using more amount of fuel than it is supposed to. How is this so? As the engine can pull in an amount of oxygen from various factors such as the load of the engine, the engine and air's temperature, the altitude, and barometric pressure, absence of the oxygen sensor's function will result to impossibly controlling the mixture. If the load of air/fuel mixture is not controlled, it can cause damage to the engine and/or produce more harmful gases. This is where the significance of this device comes into the scene, as the engine computer adjusts automatically the amount of the fuel that should enter the engine whenever the sensor detected the mixture is too rich or lean.

Rich and lean mixtures are neither healthy presence in the overall function of vehicles. Rich mixtures are detrimental to the engine as leftover fuel is unburned after combustion and will create more toxic gases, while lean mixtures will not only produce more pollutants (nitrogen-oxide elements) but will also cause the engine poor performance. However, if the oxygen sensor of your Chevrolet's engine is functioning excellently, you will avoid these dilemmas. You can detect if the oxygen sensor is malfunctioning if the engine seems not to respond quickly or shows some loss of power. In this case, you need to have a mechanic check its condition. If it proves useless already, this needs to be replaced at once to avoid encountering unlikely consequences. To locate Chevrolet oxygen sensors, Parts Train is the perfect automotive place to go.
