I had that code on my car one of two secondary smog pumps went bad and the long thin air hoses that cary the secondary air cracked in places thus losing secondary air and sounding a code. It looks like the valve can also lose its seal around its base at exaust header. Get the code diagnosed, then DIY the valves and air hoses.
