Method for operating an internal combustion engine, the internal combustion engine and a control apparatus therefor

摘要

The invention is directed to a method for operating an internal combustion engine (1) wherein a fault of a pressure system with a pressure sensor (14) is determined by a first diagnostic system (14') of the engine (1). The pressure sensor (14) is especially a pressure sensor of a high pressure fuel system of the engine. For a plausibility consideration of a pressure system fault, which is determined by the first diagnostic system (14'), at least one further diagnostic system (18') of the engine (1) is checked as to a second fault.
