Kia Sportage: Heated Oxygen Sensor (HO2S): Description and Operation

Third generation SL (2010â€“2016) / Kia Sportage SL Service & Repair Manual / Engine Control / Fuel System / Engine Control System / Heated Oxygen Sensor (HO2S): Description and Operation

Description

Heated Oxygen Sensor (HO2S) consists of zirconium and alumina and is installed both upstream and downstream of the Manifold Catalytic Converter. The sensor output voltage varies in accordance with the air/fuel ratio.

The sensor must be hot in order to operate normally. To keep it hot, the sensor has a heater which is controlled by the ECM via a duty cycle signal. When the exhaust gas temperature is lower than the specified value, the heater warms the sensor tip.
