Who told you it needs a new air pump?If it's just the air pump that is bad then i would just replace the air pump.Most of the time it's a bad combination valve.When then the engine cold and you first start it can you hear the fan come on and shut off.

There will be no symptom's for ethier they will just set the code.if the shop actual took the time to diagnose it then i would replace the pump.To check the combo valve you would take a hand vacuum pump and hook it to the vacuum nipple and see if it holds vacuum.I would go to pick a part for that pump they don't go bad often and there expensive new.Just make sure you don't miss route the hose's or you will also set that code.
