  "textContent": "A method for monitoring a pressure sensor in a direct injection system including at least one common rail, a high-pressure fuel pump, a hydraulic circuit connecting the high-pressure pump to the common rail, a passive pressure-limiting valve connected to the hydraulic circuit, configured to open once the pressure in the hydraulic circuit is greater than a threshold pressure, so as to discharge the fuel, including the steps of detecting the opening of the pressure-limiting valve, measuring the pressure Pcorresponding to the time of opening of the pressure-limiting valve and comparing the measured pressure Pto the threshold pressure Pin order to detect a drift in the pressure sensor.",
