るアイドルスイツチ用確認装置。 In an internal combustion engine equipped with an idle switch that detects the idle operating state of the engine based on the output of a throttle sensor that detects the opening degree of a throttle valve installed in an intake passage of the engine, a self-diagnosis device and an idle switch are provided. Provided with idle speed control clamping means and idle speed ignition timing fixing means for keeping the engine idle speed constant and fixing the engine idle speed ignition timing during monitor control of the self-diagnosis device,
1. A confirmation device for an idle switch in an internal combustion engine, characterized in that it is configured to confirm idle rotation when the idle switch transitions from on to off and from off to on.
