Abstract
An intake air temperature (IAT) sensor diagnostic system may include an IAT determination module, a mass air flow (MAF) module, and a diagnostic module. The IAT determination module determines a measured IAT based on an IAT sensor. The MAF module determines a reference temperature based on a MAF sensor. The diagnostic module determines faults in the IAT sensor based on a comparison between the reference temperature and the measured IAT.
