A device for sensing a side impact in a motor vehicle, the side impact sensing being performed with a deformation sensor element which is attached on a sensor bottom plate, which is in turn mounted on a side part reinforcing element with riveted connections. A temperature sensor which is also present on the sensor bottom plate detects the ambient temperature in the side part and the deformation sensor delivers a static output signal to ascertain whether the riveted connections still have a predetermined mechanical strength. If the temperature measured by the temperature sensor exceeds room temperature, the static output signal of the deformation sensor is checked with the predetermined threshold value, and if it falls below this threshold value, a defect is detected.
