Abstract
Methods and systems are provided for adjusting a voltage of a heated oxygen sensor (HEGO) so that the heated oxygen sensor is controlled to a desired temperature as the HEGO ages. In one example, a method generates a requested heated oxygen sensor electrode impedance for control and then adjusts the voltage responsive to the requested heated oxygen sensor electrode impedance for control.
