Various methods are provided for compensating changes in the relation between impedance setpoint and operating temperature in an oxygen sensor. In one embodiment, a method of operating an oxygen sensor comprises adjusting an impedance setpoint based on a change in dry air pumping current of the oxygen sensor.
