My O2 sensor light is on and I tried to get a smog and it failed and it's obvious why but there are a few electrical issues with the car and I'm just not sure if the sensor is really damaged or not. I wanted to see if I could reset it to really check if it was broken before I have to replace it. I found the info on how to test the sensor but would there be anything else that would make that light go on? I'm guessing that I should just replace the sensor. But I had a mechanic friend of mine suggest just try to reset it. What should I do?
