Task
Controlling boost pressure as a function of engine operating state
Controlling boost pressure as a function of map in IFI control module (N3/7)

Function
The boost pressure is controlled by the IFI control module (N3/7) as a function of the boost pressure map and the pressure sensor (B28). The boost pressure control vacuum transducer (Y31/5) is actuated by the control module with a variable current and supplies a controlled vacuum to the boost pressure control vacuum unit (110/10).
