Inspection

1.
Turn the ignition switch OFF.
2.
Disconnect the HO2S connector.
3.
Measure resistance between the HO2S terminals 4 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).
Note that the SST (Part No.: 09392-2H100) is useful when removing the heated oxygen sensor.

Installation

•
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.
