Abstract

A method for operating an exhaust gas mass flow sensor which is used, in particular, in exhaust gas mass flows of motor vehicles has an operating mode and a cleaning mode. In an operating mode, the exhaust gas mass flow sensor is operated at an operating temperature. In a cleaning mode, the exhaust gas mass flow sensor is changed over for the purpose of cleaning a measurement region and is cleaned at a cleaning temperature which is higher than the operating temperature.
