Location 

The pressure sensors are located behind the respective door trim.

Task 

To detect a side impact in the door area, the pressure sensors measure the air pressure values inside the doors. If the air pressure value increases significantly in one door (e.g. when the door skin is pressed in from outside), the restraint systems control unit (N2/7) triggers the respective sidebag or windowbag in the impact area.
