| Description |
Heated Oxygen Sensor (HO2S), consisting of zirconium and alumina, is installed on both upstream and downstream of the Catalytic Converter to detect the air/fuel ratio and send it to the ECM.
The sensor must be heated in order to operate properly. To keep it heated, 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 up the sensor tip.

The sensor may be limited when: - The radar or the camera is contaminated with foreign substances. - It heavily rains or snows. - There is electromagnetic interference. - Something in the path of travel deflects the radar waves. - The vehicle in front has a narrow body. (i.e. motor cycle and bicycle) - The driver's view is not clear due to backlight, reflected light, or darkness.
