Abstract
A method is provided for operating an injection system of a motor vehicle, which injection system is designed as an adjusting system having volumetric flow rate control via a normally open inlet valve. If a fault of the inlet valve leading to undesired closing of the inlet valve is detected, the inlet valve is closed already during the suction phase of the high-pressure pump by applying current and is opened again during a part of the suction phase corresponding to a pumping demand in order to thereby control or at least reduce the flow rate of the high-pressure pump. Thus, corresponding safety measures, such as a pressure-limiting valve in the high-pressure region, can be omitted.
