Original Abstract Submitted

A method and a device for diagnosing an air supply of an internal combustion engine which includes a first air duct for supplying air to a cylinder and a second air duct for supplying air to a heater for heating an exhaust system. The first and second airs ducts each have a mass flow sensor for measuring a mass of the air flowing therethrough, a pressure sensor for measuring the pressure in the air duct, and a temperature sensor for measuring the temperature of the air flowing therethrough. The first and second air ducts originate from a common air filter. Depending on operating states of the cylinders and heater, measured values of the mass flow sensors, pressure sensors, and temperature sensors of the first and second ducts are compared with one another or with comparison values, and a result of the diagnosis is ascertained depending on the comparison.
