It is proposed a method for controlling a pressure inside a fuel tank system on board a vehicle, the fuel tank system comprising a fuel tank and a venting circuit having at least one controllable pressure relief valve, the vehicle comprising 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 comprises: - detecting (S1) a key off event indicative of the vehicle shut-down; - determining (S2) an amount of energy available at the source of energy; - starting at least one pressure relief operation comprising the steps of: (i) verifying (S3) whether the amount of energy available is lower than a first predetermined threshold amount; (ii) if said verifying (i) is positive, activating said at least one pressure relief valve; - terminating said at least one pressure relief operation.
