Abstract

See full text

A diagnostic system for a vehicle comprises a humidity module and a fault diagnostic module. The humidity module outputs a first humidity value based on a humidity measurement of a humidity sensor of the vehicle and outputs a second humidity value based on humidity data from a data source that is external to the vehicle. The fault diagnostic module selectively diagnoses a fault in the humidity sensor based on the first humidity value and the second humidity value.
