Default three codes

I have a 0405 code (egr sensor low) second is 0410 (secondary air injection system fault) and 0412 ( air injection switching vavle A circuit) I was wondering if the air valve could clog up and throw the last two. I know my egr is messed up so im not so worried about the first code.

First thing to look at when P0410 and P0412 are set at the same time is for an open AIR PUMP fuse. You can look up the diagnostics for all 3 codes for your year at gearchatter.com
