摘要： An engine control system comprises a signal deviation module, a variation determination module, and a sensor diagnostic module. The signal deviation module receives a signal from a sensor monitoring an operating condition of an engine and determines a plurality of signal deviations. Each of the plurality of signal deviations is based on a magnitude of a difference between the signal at a first time and the signal at a second time. The second time is different than the first time. The variation determination module generates a variation value based on the plurality of signal deviations during a period. The sensor diagnostic module determines a state of the sensor based on the variation value.

摘要： An outside air temperature (OAT) diagnostic system includes an ambient temperature monitoring module that receives (i) an OAT signal from an OAT sensor and (ii) an intake air temperature (IAT) signal from an IAT sensor of an engine. The ambient temperature monitoring module compares the OAT signal to an IAT signal and generates a first difference signal. A performance reporting module determines whether the OAT sensor is exhibiting a fault and generates an OAT performance signal based on the first difference signal.
