Function: Oxygen sensors can be divided into front sensors and rear sensors. They mainly monitor the amount of oxygen in the exhaust and transmit the information to the engine computer to maintain higher fuel economy, reduce emissions, etc. The oxygen sensors are durable and resistant to oxidation and high temperatures, ensuring long-term stable performance. Replacing your engine's oxygen sensor can improve engine performance and fuel economy.
