Zusammenfassung:	The invention relates to a method for monitoring the operation of a fuel circuit shut-off valve comprising an LPSOV, a flow regulator, the shut-off valve, characterised in that it comprises: a step for ordering (30) the closure of the valves; a step for measuring (32) the fuel flow rate in the circuit qui carried out before the LPSOV is completely closed; and a diagnostic step (34) consisting of determining that said shut-off valve is defective if the fuel flow rate measured is not equal to zero and determining that said shut-off valve is operating correctly if the fuel flow rate measured is zero.
