摘要： A failure diagnosis apparatus for a throttle valve actuating device is disclosed. The throttle valve actuating device has an actuator for actuating a throttle valve provided in an intake system of an internal combustion engine and biasing elements for biasing the throttle valve to a predetermined retention opening. A feedback control of the throttle valve is performed so that an opening of the throttle valve coincides with a first predetermined opening. After the throttle valve is controlled to the first predetermined opening, a feedback control of the throttle valve is performed so that an opening of the throttle valve coincides with a second predetermined opening. It is determined that the throttle valve actuating device has failed when the time period during which the opening of the throttle valve remains in a predetermined determination range including the second predetermined opening, is shorter than a predetermined time period when performing the feedback control to the second predetermined opening.

摘要翻译： 公开了一种用于节气门致动装置的故障诊断装置。 节流阀致动装置具有致动器，用于致动设置在内燃机的进气系统中的节流阀和用于将节气门偏压到预定保持开口的偏压元件。 执行节流阀的反馈控制，使得节流阀的开度与第一预定开口重合。 在节流阀被控制到第一预定开度之后，执行节流阀的反馈控制，使得节流阀的开度与第二预定开度一致。 当节气门开度保持在包括第二预定开度的预定确定范围的时间段时，确定节气门致动装置已经失败，当对第二预定开度执行反馈控制时，节气门致动装置的预定时间段短 预定开口。
