EGR Backpressure Transducer: Description and Operation

Vacuum Transducer (Y31/1, Y31/4)




Y31/1 EGR Valve vacuum transducer
Y31/4 Boost pressure control 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.
