Have you tried replacing these sensors? That is what the codes indicate. When replacing the IAC that port needs to be cleaned up good also.

Rowefast is right, they probably need changed, but if you want to test them first you can go to easyautodiagnostics.com and there are step by step procedures for testing using a multi meter.
