EGR Valve Position Sensor: Description and Operation
Position
Integrated EGR valve
Task
Measuring exhaust gas recirculation quantity
Function
The EGR valve of the EGR lifting sensor (B28/3) is linked mechanically to a potentiometer. The IFI control module (N3/7) recognizes on the
basis of the voltage ratio U(suffix 3/2) / U(suffix 1/2) the lift of the EGR valve and thus the exhaust gas recirculation quantity.
