Air Injection: Description and Operation

Chart C-6 Wiring Diagram:

CIRCUIT DESCRIPTION:

This system has a single bed converter, and the air management is controlled by an air control valve (diverter valve).

When the ECM grounds the circuit, the solenoid causes the valve to direct air to the exhaust ports. When de-energized, air diverts to the atmosphere, and air will be diverted to the ports provided that the valve has grounded at the ECM, and good manifold vacuum exists.
