A redundant sensor system includes first and second sensors of the same type. The first and second sensors are configured to sense and measure a parameter, such as torque, applied to an object, such as a shaft. A preselected measurement value difference is provided between the first and second sensors. The preselected measurement value difference, such as an offset or a difference in sensor gain, can be utilized by the redundant sensor system or an associated control system to detect a failure of one of the sensors. Output signals of the first and second signals that do not reflect the preselected measurement value difference within given tolerance indicate that one of the sensors has failed, and a determination that an associated system is untrustworthy can be obtained.
