Method for diagnosing evaporative losses from a fuel tank of an internal combustion engine; the method of diagnosis consisting of: isolating the tank; pressurizing/depressurizing the tank by means of a pneumatic machine driven by an electric motor; measuring the time profile of at least one characteristic value of the electric motor; and diagnosing the rate of evaporative loss from the tank as a function of the frequency range of the characteristic value of the electric motor.
