Because I don't know what engine/year you have I can give you some generic advice.
I would replace the secondary air injection hose, clear all codes, and drive it.
There should be a check valve in or near the hose so replace that to.
If you get another code, you might have a problem with the Sec. Air Inj. Pump.
Or take it to the dealer or independent mechanic to have them diagnose and repair.
