Zusammenfassung:	PURPOSE:To improve an antinoise property and reliability and enable the display of the necessary lowest limit function even if an engine control unit is failured in a sensor integrated type engine controller. CONSTITUTION:An engine control unit 30 is provided on the same base plate as that of a crank angle sensor 26 disposed in an engine room. A failure detecting circuit and back-up circuit in the failure of the engine control unit 30 together with a power transistor circuit for driving an injector 70 and ignition system are built in an actuator of the engine, for example, the injector 70 and ignition system. When a crank angle sensor 26 united with engine control unit 30 is mounted on the base plate, about several mms of length of a conductor between both will do. Thus, the control of the engine is hardly influenced by the engine ignition noise mixed from this short conductor to provide the engine control device excellent in anti-noise property. The function of the engine control unit can be backed up by the respective actuators of the engine.
