Determines the oxygen content of the exhaust gas;Produces a voltage proportional to the amount of oxygen in the exhaust versus the air, 750 mV rich;The data is used to control the air-fuel mixture through PORT or TFI injectors and carburetors;Sensors are monitored or checked anywhere from 4 to 100 times per second;The air-fuel mixture is thus always moving from rich to lean averaging very close to stoichiometric (ideal) ratios;OE Direct Fit Sensors;100% Original Equipment Technology;Improved Engine Response And Performance;Improved Fuel Economy & Lower Emissions;Longer Sensor Life
