This isn't a 2 minute repair. This code deals with a problem in the secondary air injection system. Any of the following could be an issue:

Vacuum leak
Air Pump inoperative
Bypass solenoid harness is open or shorted
Poor bypass solenoid circuit electrical connection
Bypass solenoid leaking, plugged or stuck in an open or closed position
Diverter valve leaking, blocked or stuck in an open or closed position
