Hello , thanks for your question in the autoaid Community.
Your described fault Code means: CATALYST SYSTEM EFFICIENCY (BANK 2) ERROR
This Fault Code means the Catalytic System himself, but i think there is an other problem, because there is only an error, not an efficiency error.
So, now you should check the gasoline system, is there already okay?
Sometimes is there false air in the air intake system. Look also for this part.
Use the is values for more Infos, then talk here back to me and we could look what you can check then.
I hope that i could help from far away.
