Exhaust Pressure Regulator Vacuum Valve: Description and Operation
Vacuum Control Modulator

Fig. 49 Vacuum control modulator.

    The vacuum control modulator is composed of a pressure regulator and solenoid valve. Intake manifold vacuum is used as the vacuum source for the
pressure regulator. The passage leading to the atmosphere is controlled by solenoid valves. The vacuum control modulator provides vacuum to the EGR
valve and AAC valve following the electrical signal from the control unit.
