Patent abstract
A sensor diagnostic method, such as to determine rationality of one of three temperature sensors used in an exhaust aftertreatment system, includes determining the temperature difference between the first and second sensor, determining the temperature difference between the second and third sensor, determining whether the temperature differences are within an acceptable threshold range and comparing the two temperature differences to determine which sensor is in error, if any.
