    摘要: According to at least one aspect of the present technology, a method is provided for compensating the output of a mass air flow sensor in response to humidity level. The method includes determining an actual mass air flow value (MAF_ACT) using the mass air flow sensor. The method also includes determining an actual humidity value (HUM_ACT) of the air flow that is measured by the mass air flow sensor. The method further includes determining if the actual humidity value (HUM_ACT) is outside of a preselected operating range. If the actual humidity value (HUM_ACT) is outside of the preselected operating range, the method determines a humidity-compensated mass air flow value (MAF_HUM) as a function of the actual mass air flow value (MAF_ACT) and the actual humidity value (HUM_ACT).
