The Chevrolet Blazer oxygen sensor helps to keep your engine at its best, working with the vehicle computer to optimize its efficiency. The engine operates at its most efficient when provided with a precisely balanced mixture of fuel and air to use in the combustion process. If this the fuel and air ratio is balanced correctly, there will be just enough oxygen mixed with the fuel to burn the fuel completely during combustion, which will provide the best engine performance and power output.

The vehicle computer, using information provided by the oxygen sensor, regulates the ratio of fuel and air. Located in the exhaust system, the oxygen sensor measures the amount of oxygen left in the emissions of the vehicle after combustion to determine whether the fuel has burned efficiently.

Using a voltage signal, the Chevrolet Blazer oxygen sensor transmits its reading to the vehicle computer, which will use it to adjust the fuel and air ratio accordingly. This efficient process of monitoring and adjustment of the fuel and air ratio continues in a constant cycle as your vehicle travels, allowing your engine to run at its best in spite of changing oxygen levels in the air. The concentration of oxygen in the outside air changes constantly, due to the influence of such factors as air temperature and elevation among many others variables.
