(54) ENGINE CONTROL DEVICE, ELECTRONIC CONTROL UNIT, ELECTRONIC CONTROL UNIT CASE AND THROTTLE POSITION SENSOR


(57) It is an object of the present invention to provide an engine control device, and an electronic control unit (ECU) and ECU case constituting this engine control device, which make it possible to realize a reduction in size and reduction in cost. A throttle body 1 and an ECU case 2 which accommodates an ECU which is manufactured by a separate process from the throttle body 1 are attached by means of screws. The ECU case has internal recesses (31, 32, 33, 34) for accommodating members that protrude from one surface of the circuit board 100, including at least one sensor selected from an intake air pressure sensor, an intake air temperature sensor and a throttle position sensor (TPS), which are attached to one surface of the circuit board 100, and projections (41, 42, 43) formed on the outside of the ECU case 2 by these recesses are attached facing the throttle body 1.
