    摘要： A diagnostic system and method for detecting failures in a fuel system of a vehicle includes a fuel level monitoring module that determines a first change in a first fuel level of a first fuel tank based on data received from a first fuel level sensor and determines a second change in a second fuel level of a second fuel tank based on data received from a second fuel level sensor. A sensor diagnosing module evaluates operation of the second fuel level sensor based on the first change in the first fuel level.

    摘要： A vacuum signal diagnostic system that diagnoses operation of a vacuum sensor of a brake booster system that is in fluid communication with an engine includes a first module that determines whether a vacuum signal of the vacuum sensor is increasing and a second module that compares an engine vacuum signal of the engine to the vacuum signal. A third module indicates a HI fault of the vacuum sensor when the vacuum sensor is increasing and a difference between the engine vacuum signal and the vacuum signal is greater than zero for a first threshold time.

    摘要： An intake air temperature (IAT) sensor diagnostic module comprises a measured noise module, an expected noise module, an excess noise module, and an IAT fault detection module. The measured noise module measures noise in an IAT signal from an IAT sensor in a vehicle. The expected noise module determines expected noise based upon the IAT signal. The excess noise module determines an excess noise value based upon the measured noise and the expected noise. The IAT fault detection module diagnoses faults in the IAT sensor based upon a comparison of the excess noise value and a first predetermined value.

    摘要： A diagnostic cold start emissions control system for an internal combustion engine includes a control module having a calculated engine-out energy module, an engine-out energy residual module, and a diagnostic system evaluation module. The calculated engine-out energy module is in communication with the engine-out energy residual module and is configured to determine an operating engine-out energy flow based on an operating engine torque. The engine-out energy residual module is in communication with the diagnostic system evaluation module and is configured to determine an engine-out energy residual based on the determined engine-out energy flow and an expected engine-out energy flow. The diagnostic system evaluation module is configured to determine whether the determined engine-out energy residual meets a predetermined value indicative of proper cold start emissions control.
