A method for controlling a pressure inside a fuel tank system an board a vehicle is provided. The fuel task system comprises a feel tank and a venting circuit having at least one controllable pressure relief valve. The vehicle comprises a source of energy adapted to activate the pressure relief valve so as to move it from a closed position to a pressure relief position. The method composes 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 comprising: verifying whether the amount of energy available is lower than a first predetermined threshold amount, and if the verifying is positive, activating the pressure relief valve. The method further composes terminating the pressure relief operation.
