Kia Sportage: Engine Control System / Heated Oxygen Sensor (HO2S) Repair procedures
| 1. |
Turn the ignition switch OFF.
|
| 2. |
Disconnect the HO2S connector.
|
| 3. |
Measure resistance between the HO2S terminals 4 and 5 [B1/S1].
|
Specification: 2.5 - 4.0Ω [20°C(68°F)]
|
|
| 4. |
Measure resistance between the HO2S terminals 3 and 4 [B1/S2].
|
Specification: 3.3 - 4.1Ω [21°C(69.8°F)]
|
|
| 5. |
Check that the resistance is within the specification.
|
|
Note that the SST (Part No : 09392-1Y100 or 09392-2H100) is useful when
removing the heated oxygen sensor.
|
| 1. |
Turn the ignition switch OFF and disconnect the battery negative (-)
terminal.
|
| 2. |
Disconnect the connector (A), and then remove the sensor (B).
|
| 1. |
Turn the ignition switch OFF and disconnect the battery negative (-)
terminal.
|
| 2. |
Disconnect the connector (A), and then remove the sensor (B).
|
| • |
Install the component with the specified torques.
|
| • |
Note that internal damage may occur when the component is dropped.
If the component has been dropped, inspect before installing.
|
| • |
DON’T 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.
