Systems and methods for identifying a faulty sensor are provided. One system includes multiple sensors, each generating a first set of parameters based on detected measurands. The system also includes a fusion module for generating a second set of parameters by fusing the first sets of parameters, and a sensor fault module including multiple fault templates defining sensor faults, an estimation module for generating a third set of parameters based on the first and second sets of parameters, and an evaluation module. The evaluation module is configured to compare the third set of parameters and the fault templates, and determine a sensor fault based on the comparison. A method includes receiving a first set of parameters based on measurands from multiple sensors and a second set of parameters based on a measurand from a sensor, and determining a sensor fault based on the first and second set of parameters.
