Abstract

Described is a method for operating an internal combustion engine (1), in which method at least one parameter of the exhaust gas flowing in an exhaust-gas duct (10) is detected by at least one exhaust-gas probe (30; 32), wherein the internal combustion engine (1) is at least temporarily turned over by a starting device (3), during which an injection and combustion of fuel does not take place, and during and/or after which the exhaust-gas probe (30; 32) is adjusted.
