Secondary air pump
lists for $871 sells for $148 free delivery www.autohausaz.com
usually not the issue as you have discovered.
Fuse good relay good.
Most likely the corroded check valves. Take them apart and clean them up or get new ones. If exhaust can't get through them or they don't close the reed valves you get the sec air code.
Don't know why you went to the dealer to buy parts or why you did not test the pump motor before throwing a new part at the problem.

Live and learn
in the emissions section.
Now take off the check valves and clean then or replace. The motor is operating correct? It should click on when you start the car with the engine cold in the morning or anytime the engine is cold.
