The Mazda Oxygen Sensor, located in the engine's exhaust system, helps in regulating the air-fuel ratio in the combustion engine. If the air and fuel produce the maximum efficiency, then the ratio between the two is called a “perfect ratio”. If the amount of air is lower than that of the perfect ratio, then the mixture is rich. If the amount of air is higher, the mixture is lean. Both mixtures cause pollution and decrease the performance of your vehicle. If rich and lean mixtures are detected, the engine control unit (ECU) regulates the amount of fuel to attain maximum efficiency.
