OXYGEN SENSORS by DELPHI
Product Description
Oxygen sensors are an electronic device that monitors the level of oxygen that is present in the fuel air ratio. Oxygen sensors make modern electronic fueling injection and emission control possible because it is able to determine if the air in the fuel mixture in the combustion engine is rich or lean. Because the oxygen sensors are located in the exhaust system, they do not measure the amount of oxygen that enters the engine. By combining information from other parts of the car, oxygen sensors are able to enable electronic fuel injection to work more efficiently.
