1999 S80 OBD2 Codes P0172,175 and 1633 How to fix??? S80

It is a 1999 S80. I pulled the codes and 3 came up. P0172 which is Bank 1 system too rich and P0175 Bank 2 too Rich. Then P1633 which my scanner said Auxiliary something out of range.... That isn't exactly what it said but close. Does anyone know what this means and how to fix this problem this? I had a few other codes before but I cleared them and they haven't come back but just for the record they were P0722 Output Speed Sensor and P1618 another Auxiliary Code. Any info would be appreciated. Thanks.
