Abstract
A method for calibrating an exhaust gas sensor arranged in a measurement chamber, includes providing a measurement chamber in or adjacent to an exhaust channel of an internal combustion engine. At the start of a calibration phase, exhaust gas present in the measurement chamber is displaced by a filling of the measurement chamber with calibration gas, and at the end of the calibration phase, exhaust gas diffuses into and/or is introduced into the measurement chamber.
