Abstract
In an abnormality detection apparatus for vehicle engines, a deceleration discriminating circuit discriminates a deceleration state of a vehicle engine on the basis of a running state of the engine detected by a running state detector for detecting a running state of the vehicle engine. When the deceleration discriminating circuit determines that the engine is being in deceleration state, a comparing circuit compares a vehicle speed detected by a vehicle speed detector with a predetermined value. An abnormality deciding circuit is responsive to a comparison result signal from the comparing circuit to decide abnormality of the vehicle speed detector.
