Abstract
A system and method for detecting a stuck or malfunctioning fuel tank level sensor calculates an estimated fuel tank level sensor value and compares the estimated sensor value with the actual sensor value. Upper and lower threshold values may also be determined along with the estimated value. If the actual sensor value falls outside the threshold values, the sensor is considered faulty and an error signal is set in the system. The system also compares the actual sensor value with a reference sensor value to detect whether the fault is due to a stuck sensor or due to a different type of sensor malfunction.
