A method for controlling a pressure inside a fuel tank system on board a vehicle, the fuel tank system having a fuel tank and a venting circuit having at least one controllable pressure relief valve, the vehicle having a source of energy adapted to activate said at least one pressure relief valve so as to move it from a closed position to a pressure relief position. The method entails: detecting a key off event indicative of the vehicle shut-down; determining an amount of energy available at the source of energy; starting at least one pressure relief operation by verifying whether the amount of energy available is lower than a first predetermined threshold amount and, if the verification is positive, activating the at least one pressure relief valve; and terminating the at least one pressure relief operation.
