A method for operating an internal combustion engine. The internal combustion engine has at least one cylinder, to which are connected an intake manifold having an air mass sensor, an exhaust pipe having a λ-sensor and an exhaust gas recirculation line having an exhaust gas recirculation valve. The air mass sensor generates an air mass sensor signal. The λ-sensor generates a λ-sensor signal. The exhaust gas recirculation valve is adjusted by a control signal. A setpoint injection quantity is formed and the control signal of the exhaust gas recirculation valve is formed as a function of the air mass sensor signal. An air mass replacement signal for the air mass sensor signal is formed as a function of the λ-sensor signal and the setpoint injection quantity. In the case of a faulty air mass sensor signal, the control signal is formed as a function of the air mass replacement signal.
