Herein provided are methods and systems for detecting in-range faults for a sensor of an aircraft engine control system. A plurality of in-range values produced by the sensor are received. At least one rate reversal event, indicative of a variation in the rate-of-change of the plurality of in-range values exceeding a predetermined variance threshold, is detected. A count of rate reversal events during a predetermined time period is determined. A faulty status to the sensor is assigned based on the count of rate reversal events exceeding a predetermined limit.
