Abstract
A fuel evaporative emission control apparatus executes a first leak presence/absence determination for determining the presence or absence of leaks of fuel evaporative gases based on the detection results of a tank pressure detection portion, with a first opening/closing portion being closed, a second opening/closing portion being opened, and a third opening/closing portion being closed. The fuel evaporative emission control apparatus can determine whether leaks of fuel evaporative gases are present or absent, can pinpoint the location of the leaks, and can detect a sensor abnormality.
