Delphi oxygen sensors feed data to the ECM which helps the engine to run as efficiently as possible while maintaining fuel mileage and reducing emissions. Because the amount of oxygen the engine pulls in can vary due to altitude, air temperature, engine load, the oxygen sensors optimize combustion by monitoring oxygen levels, so that the proper amount of fuel can be combined with the air.
