Can someone give me an idea what a secondary air injection malfunction might be? I got the check engine light today and scanned it with my code reader. The code was p0410.

secondary air feeds air into the catalyst for emissions control. Is fed this air by a belt driven air pump mounted on the engine.

could be anything from the air pump not flowing, to a leak in a pipe or hose or the sensors that tell the pcm when to turn it on or wires to/from said sensors.
