Abstract
A method for operating an exhaust gas sensor, which has at least two electrodes, between which a pump current flows and between which a pump voltage occurs, said sensor being operated with a nominal operating temperature and a low temperature operation being intermittently provided at said sensor, wherein the temperature of the exhaust gas sensor is less with respect to the nominal operating temperature, and a device for carrying out the method are proposed. Provision is made according to the invention for the pump voltage to be acquired and for the low temperature operation to be influenced by the pump voltage.
