Method and device for the control of an internal combustion engine

The method involves measuring engine combustion air pressure with an induction pipe pressure sensor and passing a sensor signal corresponding to instantaneous pressure to a controller, which derives a control signal the air-fuel mixture fed to the engine. The gradient of the induction pipe sensor actual characteristic is detected, a deviation from a desired characteristic is determined and a correction value derived for the pressure sensor signal. Independent claims are also included for the following: an arrangement for regulating an internal combustion engine.
