Abstract (en)
[origin: JPH04214949A] PURPOSE: To provide an electronic control device for an internal combustion engine of a car capable of monitoring over a wide range the failure of a sensing device to sense the operating parameters for the engine. CONSTITUTION: A sensing device is connected with a member to set the output of an internal combustion engine, in particular a throttle valve, control rack or accel. pedal, and generates at least two signals. The signals are formed so that at least two position signal values vary in the opposite direction to each other when the position of the member to set the output has varied. According to this configuration to perform failure sensing, it is possible to sense a shunt or shortcircuiting between sliders 24 and 26 of a potentiometer in case the sensing device is formed as a double type potentiometer (P1 and P2).
