Hyundai Accent (HC) (2017 - 2022) Service Manual: Heated Oxygen Sensor (HO2S)

- Description Heated Oxygen Sensor (HO2S) consists of zirconium and alumina and is installed on upstream and downstream of the Warm up Catalytic Converter (WCC).After it compares oxygen consistency of the atmosphere with the exhaust gas, it transfers the corresponding voltage signal to the ECM.In order that this sensor normally operates, the temperature of the sensor tip must be higher than predetermined temperature.
