Abstract
Methods and systems are provided for adapting a target impedance of an oxygen sensor. In one example, a method may include updating a target impedance of an oxygen sensor based on a difference between an estimated voltage across a sensing element of the oxygen sensor and a reference RMS voltage of the sensing element. The temperature of the oxygen sensor may be adjusted based on the updated target impedance.
