Charging pressure sensor

The charge-air pressure sensor registers the absolute pressure (total of charge-air pressure and ambient pressure) in the exhaust system and serves as a sensor for the charge-air-pressure control.

The charge-air pressure sensor is mounted directly on the air collector for intake air. The DDE control unit provides the charging pressure sensor with ground and a supply voltage of 5 V.

The pressure is picked up via a bore hole in the sensor and a corresponding measured voltage is sent to the DDE control unit.
