I had Oxygen Sensor Engine Light that complained about the Bank 1 Sensor 1. I used my OBD2 tool to clear the code, and the engine light is not coming back.
Can I leave the sensor as is or still I should replace it since I had the OBD engine code at least once?
Update after a week
The engine light came back. Lesson learned: Once you see the code, the sensor needs to be changed.
I replaced the sensor and the engine light is gone for good.
