    OBD Code P0418?

    Hello,

    I was wondering if anyone has had any experience with code P0418 (Secondary Air Injection System Relay ĎA" Circuit Malfunction)...

    Is this just a relay or electrical component that needs to be replaced? I'm not sure where to start here... Any advice is appreciated.

    Thanks!

    It could be the AIR pump fuse ?? or check valve.
