Hi and thank you in advance for your help! I had the above trouble codes on my car a few days ago. I had the B1S2 O2 sensor replaced yesterday. The CEL came back on and now I have the exact same trouble codes. I have the descriptions for each and the only thing they have in common is "check circuit fuse". I thought I checked all the fuses for the O2 sensors but maybe not. Do you have any idea what it would likely be with both codes popping up?

That si the same sensor there is possibly a short to ground in wiring check fuses underhood for this. It may need a pro to check this though to find the short.

Thank you! I actually found out that the Bosch O2 sensor I had put in has a pretty foul history. Most people say the heater resistance is incorrect and you have to buy either AC Delco or Delphi. Since both trouble codes say something about the heating conditions in the O2 sensor, I'm going to order the Delphi or AC Delco sensor and have them put it in. The mechanic I use said it could be a number of different things and wants to charge me $80 per hour for basically 8-12 hours. At the end of the conversation he said, "unless you bought Bosch, then it's probably the sensor".

Thank you for all of your help! Much appreciated!
