A method for operating an internal combustion engine, in which at least one first influence variable influences a state variable of the air in the intake manifold. The state variable of the air in the intake manifold is ascertained while taking into account a plurality of influence variables, which influence the state variable, while using a first physical relationship. The same state variable is ascertained while taking into account a plurality of influence variables, which influence the state variable of the air in the intake manifold while using a second physical relationship. A specific adjusting parameter, which represents a specific error in the influence variable, is linked to each influence variable. The adjusting parameters are learned and monitored in the operation of the internal combustion engine. A certain adjusting parameter is learned and monitored in an operating range of the internal combustion engine in which the other adjusting parameters have a lesser influence on the state variable than that certain adjusting parameter, and in this context, the certain adjusting parameter is adjusted in such a way that the state variable ascertained by using the first physical relationship is at least approximately equal to the state variable ascertained by using the second physical relationship.
