Bosch Oxygen Sensor for Cat
I decided to replace my down stream cat O2 sensor. I didn't have any error codes but I decided to try it anyways. I purchased the downstream Bosch Universal one today and installed it. White to White (times 2), Black to Black, and Gray to Gray. I turned it on and I get a code now. I said maybe it might be a bad one from the store so I brought my car to advance auto parts and they pulled up Bank 1 Sensor 2. I purchased another one to install and the same thing. I also installed a new primary O2 sensor as well but it seems like it works fine because the car drives normal. My car is a 2000 anyone with any ideas? Did I put the wrong wires together?

The guy at advanced auto said it didn't show. He said it showed bank 1 sensor 2. I'm thinking I am going to another one tomorrow morning to try again. If my primary o2 sensor was bad, would my car be running normal?
I think I am going to invest in an ODB2 scanner tomorrow as well.

I got it rescan and its a P0141. Did I wire it wrong? I tried 2 brand new sensors. Both the harness and the bosch oxygen sensor was 2 white wires, 1 gray wire, and 1 black wire.
