The Scion Oxygen Sensor monitors the ratio of air and fuel in the exhaust and reports it to the engine control unit (ECU). The ratio of air and fuel that gives maximum efficiency is called a “perfect ratio”. There are two possible mixtures of air and fuel in the combustion chamber: rich and lean. The mixture is rich when the amount of air is less than that of the perfect ratio and is lean when there is excess air than that of the perfect ratio. If these mixtures are detected, the fuel injection is regulated to maintain a perfect air-fuel ratio.
