1998 Ford Taurus

I just diagnosed my '98 Taurus w/ code PO411, Secondary Air Injection System-Incorrect Flow. Does anyone know anything about this code? Cost to fix? Can I do it myself w/ limited mechanical abilities? Any details would be appreciated

Remove the pump that is located on the lower drivers side of radiator. See if water comes out of the air intake snorkel. If water comes out, replace assembly.

If it is pumping sor a few seconds then quits, it is operating properly. I would look for a wiring problem or a connector. It possibly could be the switching solenoid located on the drivers side of motor hid under the air intake snorkel.
