Kia Optima Hybrid: Engine Control System / Heated Oxygen Sensor (HO2S) Repair procedures

Inspection
1.
Turn the ignition switch OFF.
2.
Disconnect the HO2S connector.
3.
Measure resistance between the HO2S terminals 4 and 5 [B1/S1].
Measure resistance between the HO2S terminals 3 and 4 [B1/S2].
4.
Check that the resistance is within the specification.

Installation
   
Install the component with the specified torques.
Note that internal damage may occur when the component is dropped. In this case, use it after inspecting.
   
Do not use a cleaner, spray, or grease to sensing element and connector of the sensor because oil component in them may malfunction the sensor performance.
Sensor and its wiring may be damaged in case of contacting with the exhaust system (Exhaust Manifold, Catalytic Converter, and so on).
1.
Install in the reverse order of removal.
