Anyone had this code before?

My check engine light just recently started going off and on, i put my scan tool on it and the code it gives is a "secondary air valve malfuction" any ideas as to what that is?

What is the code number?

My scanner doesnt give the code number, it is supposed to eliminate the need for a number book and all that. It is my dads scanner he spent a few hundred bucks on for his work.

Sounds like some kind of emissions control. You don't need emissions.
