Abstract

A method for determining the operability of at least one pressure sensor of an internal combustion engine of a motor vehicle, in which the ambient pressure is first determined by the pressure sensor, and the ambient pressure determined by the pressure sensor is then compared to the ambient pressure determined by a reference pressure sensor not belonging to the internal combustion engine.
