ABSTRACT:
In order to obviate rapid on/off hunting of an engine idle detection circuit which is operatively connected with a throttle valve position sensor, the detection circuit outputs an idle indication when the throttle valve opening is indicated as having fallen below a first predetermined level which is proximate the fully closed one. The idle indication is maintained until such time as the throttle valve is indicated as having opened beyond a second predetermined level which is slightly greater than the first one.
