    You need to get the actual codes. Bank 1 is drivers side, Bank 2 is passenger side - Sensor 1 is precat, Sensor 2 is post cat. If it's for catalyst inefficienty (P0420) remember the cats are covered under warranty for 10yrs/120K on the 00-02 cars - might be the 02 is just letting you know the cat is bad.
