Abstract

An engine throttle valve position detector has a throttle switch formed by a rotary detector member rotatable with the engine throttle valve, a single stationary contact and a single movable contact movable by a guide groove in the rotary detector member into and out of electrical contact with the stationary contact. The stationary and movable contacts are contacted together when the throttle valve is in both fully-closed and fully-open positions, to thereby emit electric signals to an electric control unit in which the signals are processed on the basis of engine intake air flow and engine oil temperature to judge one of the throttle valve fully closed and fully-open positions.
