In late 2006 I had the P0410 code diagnosed and repaired on my Aurora...they replaced the air pump and then there was a valve that kept sticking on it so then they replaced that. Anyway, the code is back on. I really hate to think that the pump is bad after less than 2 years (since they said it was only a 12 month warranty). Other than a bad pump or valve sticking shut, what else could it be?
