Re: 2002 Corvette
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.
