Front HO2S Current Inspection
- Warm up the engine to normal operating temperature.
- Using the WDS or equivalent, verify that the current of the front HO2S (WDS PID: O2S11) is as indicated in FRONT HO2S CURRENT .
- If it cannot be verified even though the related harnesses have no malfunction, replace the front HO2S. (See FRONT HEATED OXYGEN SENSOR (HO2S) REMOVAL/INSTALLATION .)
