Variable Boost Control Solenoid: Description and Operation
Vacuum Transducer (Y31/1, Y31/4)
Y31/1 EGR Valve vacuum transducer

Respective to operating conditions, the vacuum transducers receive a control current from the control unit. The vacuum transducers then deliver a
corresponding amount of vacuum for the EGR valve or the boost pressure control valve.
