    • An ECU calculates actual intake air quantity suctioned into a combustion chamber or a value correlated with the actual intake air quantity as an actual measurement data based on a measurement value of an airflow meter. The ECU calculates intake air quantity estimated to be suctioned into the combustion chamber or a value correlated with the estimated intake air quantity as an estimation data based on a drive state of a throttle actuator. The ECU detects an abnormality in the throttle actuator based on a deviation degree between the actual measurement data and the estimation data. In the abnormality detection, the ECU changes at least one of an abnormality determination value used in the abnormality determination using the deviation degree, the actual measurement data and the estimation data based on a fuel property sensed with a fuel property sensor.
    • ECU基于气流计的测量值,计算吸入燃烧室的实际吸入空气量或与实际吸气量相关的值作为实际测量数据。 基于节气门执行器的驱动状态,ECU将估计为吸入燃烧室的进气量或与估计进气量相关的值作为估计数据进行计算。 ECU根据实际测量数据和估计数据之间的偏差程度来检测节气门执行机构的异常。 在异常检测中,ECU基于利用燃料特性传感器检测到的燃料特性,使用偏差度,实际测量数据和估计数据来改变在异常判定中使用的异常判定值中的至少一个。
