Air Injection Diverter (AIR Diverter) Valve
The secondary air injection diverter (AIR diverter) valve is used with the electric AIR pump to provide on/off control of air to the exhaust
manifold and catalytic converter. When the electric AIR pump is on and vacuum is supplied to the AIR diverter valve, air passes the integral check
valve disk. When the electric AIR pump is off, and vacuum is removed from the AIR diverter valve, the integral check valve disk is held on the
seat and stops air from being drawn into the exhaust system and prevents the back flow of the exhaust into the Secondary Air Injection System.
Solid State Relay
Solid State Relay
The solid state relay switches the high current required for operation of the electric AIR pump. Input control to the solid state relay comes from the
powertrain control module (PCM).
