Abstract
A diagnostic system and method for detecting failures in a fuel system of a vehicle includes a fuel level monitoring module that determines a first change in a first fuel level of a first fuel tank based on data received from a first fuel level sensor and determines a second change in a second fuel level of a second fuel tank based on data received from a second fuel level sensor. A sensor diagnosing module evaluates operation of the second fuel level sensor based on the first change in the first fuel level.
