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
[Bank 1 / Sensor 1]
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.: 09392-1Y100) is useful when removing the heated oxygen sensor.
[Bank 1 / Sensor 2]
1. | Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2. | Remove the console side cover (A).
3. | Disconnect the connector (A).
4. | Remove heated oxygen sensor (A).
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. | Installation is reverse of removal.
Heated oxygen sensor installation: 39.2 ~ 49.1 N.m (4.0 ~ 5.0 kgf.m, 28.9 ~ 36.2 lb-ft)
