Code P0230 is the Fuel Pump Relay Control Circuit.
Code P0121 is Throttle Position Sensor 1 Performance and correlates with code P0068 Throttle Body Airflow Performance.
Since it is prominately electrical, you may get it under wrranty. Make sure you tell them that the P0121 code came up as soon as you bring it in and if the bring up the P0068 code argue that it did not come up in scan and if they scan it tell them you want to see it come up. The reason for this is that it may need cleaning and then would not be covered under warranty.
You might pull the intake off at the throttle body and see how dirty the intake looks with the butterfly valve open looking into the tract past it. If it is dirty, you may just need to clean it. But, don't touch it until you take it to dealer first. Then clean it and take it to another dealer if code3 comes up again as cleaning it may get the codes to drop because they are performance and it may be that the butterfly is sticking and won't close all the way.
