Zusammenfassung:	Disclosed is an aircraft sensor fault detection system. The system includes a sensor system (102) having a sensing apparatus (102) to measure a parameter of an environment and a measurement circuit coupled to the sensing apparatus. The system includes a source of alternating current (120) connected to the sensor system. The system further includes an alternating current measurement system that measures alternating current passing through the sensor system (105) and indicates an error when a threshold based on a change in impedance of the sensing apparatus is exceeded.
