I cannot conceieve of any reason why you would require a whole new throttle body. Call the dealer and ask them precisely why you need a new one, take notes and then post it here.
Exactly.
If anything maybe you need a new sensor or gasket.
The Throttle body will not throw a code it'self, a sensor on it will though.
Find out what the code is and post that up also.
