Default Code P0492?
My 2004 C5 had a check engine light with the code P0492. I looked up the code but it doesn't exist in any list I have. Does anyone know what it means? It only happens when I open her up and hit the 100mph mark, but not always. Thanks.

I believe it is Secondary Air Injection System, Is it an H or C code?

I have both H & C on the code. What part actually needs to be fixed? Or can I ignore it?
