ABSTRACT:
A device for detecting the amount of intake air for an internal combustion engine, which comprises a detect control circuit provided on the outer periphery of a member which forms an intake air path and which detects the amount of the intaken air, the detect control circuit having a pressure sensor and a second waveform shaping circuit which shapes and produces a difference between the output signal of the pressure sensor and the output signal of a low-pass filter. A pressure take-out port of the pressure sensor is so located as to detect the pressure in the outer periphery of the member which forms an air path, and the member and the detect control circuit are contained in the air cleaner.
