装置。 An electronically controlled fuel injection device that includes a hot wire intake air amount sensor and a control circuit that processes signals from a plurality of sensors that detect the operating state of the engine and controls the fuel injection amount based on the signals, An output reference value of the hot-wire intake air amount sensor is set in advance when the engine is in a normal setting state, and the output value of the intake air amount sensor when the operating state is approximately the same as the operating state for which this reference value is set is set to the reference value. The invention is characterized in that a correction means is provided for correcting the difference between the output value of the intake air amount sensor and the reference value when the output value is outside a predetermined setting range including the reference value. Electronically controlled fuel injection device.
