Feedback Control Solenoid: Description and Operation
Vacuum Solenoid/Regulator

Fig. 27 Vacuum regulator solenoid

    This regulator, Fig. 27, is used to control vacuum to the 6500 feedback carburetor on 2.3 liter engines. During engine operation, the manifold vacuum
signal is reduced to a variable vacuum output signal. The vacuum output signal is varied in response to an electric input from the MCU module. The
vacuum signal from the vacuum regulator/solenoid varies the air fuel ratio in the carburetor.
