how does an oxygen sensor work

An oxygen sensor, also known as an O2 sensor, is a crucial component of a vehicle's exhaust system. It works by monitoring the amount of oxygen in the exhaust gases and sending this data to the engine control unit (ECU). This information is used to adjust the air-fuel mixture to optimize combustion efficiency and reduce harmful emissions. The sensor uses a chemical reaction between the oxygen in the exhaust gas and a ceramic cell at its tip to generate a voltage signal. The ECU interprets this signal to determine if the air-fuel mixture is too rich or too lean, and makes adjustments accordingly. Our high-quality oxygen sensors are designed to provide accurate and reliable data to ensure optimal engine performance and minimize environmental impact. With easy installation and durable construction, our oxygen sensors are the perfect solution for maintaining the efficiency and environmental friendliness of any vehicle.
