Boost pressure sensor: Notes

The charge-air pressure sensor registers the absolute pressure (charge-air pressure and atmospheric pressure together) in the exhaust system and serves as a measured value generator or charge-air pressure control.

The charge-air pressure sensor is mounted directly on the intake air manifold and sealed off with an O-ring. The DDE control module 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 module).
