You should really find out what code your car is throwing.
That way we can give you more specific help.
Other than guessing, there is no other way...
OK, so in another post GS400 "cats"
maybe this picture will help

That IS what to do about the code, replace the # 2 sensor in bank 1. The picture shows what you need to replace and where it's located. Once you replace the sensor disconnect the battery for about ten minutes and you should be back to normal.
Alright, thanks for everything guys. Sorry I am a bit of a noob I was just confused when

most likely the code will be for 02 sensor heater circuit malfunction. that means the sensor is still good but the internal heater is bad. that will cause you to waist a lil more gas when the engine is cold but will run fine after the engine hits operating temp. i have codes for the heater circuit on all 4 of my sensors i fixed the light by removing the dash and unplugging the light for check engine lol. if it is a heater circuit code it is not to severe and will not damage anything
