My check engine light has been illuminated for about a month now, I got a friend to pull the code a couple days after it came on. It was P0410 "Secondary Air Injection System". I guess some sort of malfunction..? Has anyone had a similar problem or know what I'm going to have to do to get this fixed? I've been driving for a month with this light on and it hasn't effected the performance of the car. It's the blinding amber light I can't stand

Hopefully someone can help!! Thanks ya'll!
