Automotive oxygen sensor is the heart of the vehicle's ECU. It is used to detect the oxygen concentration of the exhaust gas. The data measured is converted into an electrical signal that ECU uses to control the fuel injection and adjust the air-fuel ratio(AFR) for optimum. combustion efficiency and the harmful exhaust gases(such as CO. HC and Nox)minimization. So that we can realize reducing the pollution and improving fuel economy.
