A method is provided for identifying an averaged sensor value of a state variable of an air system for an internal combustion engine in a motor vehicle, comprising the following steps:

Method and apparatus for furnishing a filtered air system state variable in a control unit of an internal combustion engine

For diagnosing a proper functioning of an auxiliary heater in an air mass sensor in an engine system including an internal combustion engine, the auxiliary heater being used for preventing contamination of a sensor area, the air mass sensor communicating air mass information via a signal line during a sensor operating mode and, if a specified state on the signal line is detected, activating the auxiliary heater, the following are performed: setting the state of the signal line to the specified state for a predefined time period in an auxiliary heater operating mode; transmitting a first temperature information before the activation of the auxiliary heater operating mode and a second temperature information via the signal line after expiration of the predefined time period; and detecting the proper functioning of the auxiliary heater depending on the difference between the first temperature information and the second temperature information.
