Kia Cee'd Service Manual / Fuel System / 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 2 and 5 [B1/S1].
4.
Measure resistance between the HO2S terminals 3 and 4 [B1/S2].
5.
Check that the resistance is within the specification.
Specification: Refer to “Specification”
Removal
1.
Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2.
Disconnect the connector (A), and then remove the sensor (B).
