Scanned the Camaro need advice!

I scanned my Camaro, and these numbers came up:

P0410 = Secondary Air Infection System Malfunction
P0412 = Secondary Air Infection System Vavle A Malfunction

Could someone please explain to me what this means? And if you know how to fix the problem that would be really appreciated. Ive got a Haynes repair manual too so ya let me know what to do. :)

Thanks!
