PROBLEM TO BE SOLVED: To provide an electronic fuel injection engine solving a problem caused by clogging of liquid fuel in an intake pressure inlet passage. SOLUTION: In the electronic fuel injection engine, an intake pressure sensor 4 communicates with an intake passage 2 through the intake pressure inlet passage 3, a fuel injector 5 faces the intake passage 2 at a portion downstream a throttle valve 1, the intake pressure sensor 4 is incorporated with a fuel injector 5 through a control means, and an injection amount of the liquid fuel 5a injected from the injector 5 is adjusted by the control means based on the detection of the intake pressure by the intake pressure sensor 4. At least a pair of intake pressure inlet passages 3, 7 is provided in the intake passage 2. A tip end opening 3a of the first intake pressure inlet passage 3 faces the intake passage 2, and a terminal end 3b thereof communicates with the intake pressure sensor 4. A tip end opening 7a of the second intake pressure inlet passage 7 faces the intake passage 2, and a terminal end 7b thereof communicates with a middle portion of the first intake pressure inlet passage 3a through a communication passage 8.
