Abstract
In a method for operating a heatable exhaust-gas sensor, which supplies at least one measuring signal and in which a sensor heater is operated using a pulse-width modulated operating voltage, the detection of the at least one measuring signal has priority over the supply of the pulse-width modulated operating voltage for sensor heater, and at least during a predefined time window in which the measuring signal is detected, the supply of the pulse-width modulated operating voltage for the sensor heater is suppressed using a blocking signal.
