ABSTRACT:
In a method for operating an internal combustion engine, a sensor for detecting and/or an actuator for setting a performance quantity of the internal combustion engine is/are monitored for the presence of a malfunction. Monitoring is performed at a first operating point of the internal combustion engine at a lower load and at an operating point of the internal combustion engine at a higher load. The two operating points are set alternatingly, and at least one of the two operating points is set multiple times for a single monitoring operation.
