2003 Mazda Protege 4 cyl Two Wheel Drive Automatic

Where is the BANK 1 SENSOR 2 Oxygen sensor located on the 2003 Mazda Protege. I found 2 of them one is on the top front mounted on the engine and the other is underneath mounted on the exhaust pipe. Can you tell me which one is Bank 1 Sensor 2.

Thanks,
Domingo

I'm not really sure about the code, the diagnostic showed code 1 but said bank 1 sensor 2. Is this still the one after the CAT? Thanks for your help and quick answer.
