Hyundai Santa Fe: Engine Control System / Heated Oxygen Sensor (HO2S). Description and operation
Heated Oxygen Sensor (HO2S) consists of zirconium and alumina and is installed
both upstream and downstream of the Manifold Catalytic Converter. It 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.

WARNING
To reduce the risk of an air bag deploying unexpectedly and causing serious
injury or death:
Do not hit or allow any objects to impact the locations where air
bags or sensors are installed.
Do not perform maintenance on or around the air bag sensors. If
the location or angle of the sensors is altered, the air bags may deploy when
they should not or may not deploy when they should.
Installing bumper guards with nongenuine Hyundai or non-equivalent
parts may adversely affect the collision and airbag deployment performance.
Press the Engine Start/Stop button to the OFF or ACC position and
wait for 3 minutes when the vehicle is being towed to prevent inadvertent air
bag deployment.
Have all air bag repairs performed by an authorized HYUNDAI dealer.
