Abstract
A method for checking a function of an outlet valve of an internal combustion engine includes sensing an exhaust gas pressure in an exhaust section of the internal combustion engine. The sensed exhaust gas pressure is compared with a comparison value so as to provide a comparison result and the function of the outlet valve is evaluated as a function of the comparison result.
