異常検出装置。 a throttle sensor that outputs a voltage according to the opening degree of a throttle valve that is opened and closed via a wire connected to the accelerator pedal; an accelerator pedal fully open detection means that detects a fully open state of the accelerator pedal;
A fully open output voltage detection means reads the throttle sensor output voltage when the accelerator pedal is fully opened, and a comparison determination means compares the fully open output voltage with a predetermined value to determine whether there is an abnormality in the operation of the throttle valve. Features: Throttle valve malfunction detection device for internal combustion engines.
