Abstract
An engine control system comprises a model pressure determination module and a sensor diagnostic module. The model pressure determination module determines a modeled fuel rail pressure based on an injection duration of a fuel injector and a desired fuel mass injected by the fuel injector. The sensor diagnostic module generates a status of a fuel rail pressure sensor based on a comparison of the modeled fuel rail pressure and a sensed fuel rail pressure.
