The boost pressure sensor registers the absolute pressure (boost pressure and atmospheric pressure together) in the intake system for all cylinders and serves as a measured value transmitter for boost pressure control.
The boost pressure sensor is mounted directly on the intake air manifold and sealed off with an O-ring. The DDE control unit supplies the sensor with ground (M_LDF) and a supply voltage of 5 V (U_LDF).
The pressure is picked up by a hole in the sensor and a corresponding measurement voltage (A_LDF) is sent to the DDE control unit).
Fault codes 0235 and 0236 "boost pressure sensor" are stored if the boost pressure sensor is defective.
