A method is provided for operating an aircraft system. During this method, a shaft of an aircraft powerplant is rotated. A torque signal is received indicative of a torque applied to the shaft while the shaft is rotating. A noise parameter is determined indicative of noise in the torque signal. A fault is identified in the torque signal when the noise parameter is equal to or greater than a threshold.
