In this video I’m gonna be doing a complete diagnose to see what’s wrong with the Secondary Air Injection System, which is part of the emission test. I’m gonna be explaining how to check the Air Pump, how to test the Relay with a simple multimeter, check the EGR/check valve with just a vacuum pump, vacuum line, vacuum control valve.
