The Chevrolet Astro Van oxygen sensor is a tiny component that plays a large role in the efficient operation of your vehicle. Your engine achieves its best level of efficiency and performance when given a precisely balanced fuel and air mixture, calibrated to provide just enough oxygen to burn the fuel completely. This clean burn of fuel maximizes the power output and fuel efficiency of the engine, while minimizing the pollution produced by the combustion process.

The oxygen sensor is generally found in the exhaust pipe of the vehicle, positioned to monitor the amount of oxygen left over after combustion to be sent out through the exhaust system. This reading helps to determine whether that ideal clean burn of fuel has been accomplished.

The Chevrolet Astro Van oxygen sensor uses a voltage signal to transmit its information to the vehicle computer, allowing it to adjust the fuel and air ratio as necessary to optimize the performance of the engine. The monitoring and adjustment of the fuel and air ratio is an ongoing cycle as the engine runs, allowing the vehicle to compensate for changes in the oxygen concentration in the air that often occur due to differing temperatures and elevation, along with a range of other variables. Should the sensor become unable to transmit its signal, the vehicle computer will have no basis to adjust the fuel and air ratio appropriately, causing poor vehicle performance.
