    摘要: A system includes an out of correlation (OOC) detection module that detects an OOC error between a first throttle position sensor (TPS) and a second TPS. An out of range (OOR) detection module that detects first and second OOR errors for the first and second TPS, respectively. An OOC counter sets an OOC error when an OOC count is greater than or equal to a first OOC value. An OOR counter sets first and second OOR errors when first and second OOR counts, respectively, are greater than or equal to a second OOR value that is less than the first OOC value. A control module increments the counters when the respective errors occur and sets at least one of the first and second OOR counts equal to the OOC count when at least one of the first and second OOR errors occur after the OOC error.

    摘要: A control system for regulating operation of a first vehicle system includes first and second sensors that respectively monitor first and second operating parameters of a plurality of operating parameters, and a module that receives signals generated by the first and second sensors. The module accesses a look-up table that is normally provided to determine a first one of the plurality of operating parameters based on a second one of the plurality of operating parameters and an actual value of an input parameter. The module determines a virtual value of the input parameter while the actual value of the input parameter is equal to zero At least one of the first and second vehicle systems is normally regulated based on the input parameter. The module regulates operation of the first vehicle system based on the virtual value of the input parameter.
