So I went to AutoZone to get my car diagnosed to find out why my check engine light is on and they said it was -- Secondary HO2S12 (Heated Oxygen Sensor - Bank 1 Sensor 2) circuit heater malfunction. Now, I'm not a huge car expert by any means and I am not really sure where to start looking for this. They said it might be either an open or short circuit (which I don't know how to fix) a poor electrical connection (which I probably don't know how to fix) or just a faulty HO2S12 in Bank 1 Sensor 2 (which I definitely do not know how to fix). So ANY help would be greatly appreciated. I'm just a college kid looking for a way to make my car last a little longer. If anyone has any advice on this topic or anything else please feel free to post. Thanks.
