Oxygen Sensor

Oxygen Sensors, found within the Exhaust system of passenger cars and commercial vehicles, are critical components for monitoring the amount of oxygen in the exhaust gases. These sensors send data to the vehicle's engine control unit (ECU) which then adjusts the air-fuel mixture for optimal combustion, ensuring efficient engine operation and minimized emissions. Typically located before and after the catalytic converter, oxygen sensors utilize a zirconia element to generate a voltage based on the oxygen content. Proper functioning is essential for maintaining fuel economy, reducing harmful pollutants, and passing emissions tests. Examples within our assortment include Febi MPN FEBI171274 and Bosch MPN 0258007070, catering to a wide range of vehicle makes and models.
