A vehicle door is provided with a pressure sensor within a cavity in the door. The pressure sensor is coupled to a processor and is configured to determine the air pressure within the cavity of the door. The vehicle also includes an atmospheric air pressure sensor coupled to the processor. When the door is closed with enough of a force, the air pressure changes within the cavity. During this time, the processor is programmed to receive air-pressure signals from the pressure sensor. The processor recognizes a fault in the pressure sensor if the pressure sensor does not detect a change in air pressure that varies from the atmospheric pressure by more than an expected amount when the door closes.
