Impact Pressure Sensor
WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
An impact pressure sensor is installed in each front door, attached to the door closing panels. The pressure sensors allow the RCM to detect any sudden pressure pulse that occurs in the front door during a side impact.
