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 a fuel pump flow rate and an engine fuel flow rate. 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 sensed by the fuel rail pressure sensor.
