Abstract

See full text

Methods and systems are provided for adjusting a rate of change in a reference voltage of an oxygen sensor. In one example, a method may include gradually increasing a reference voltage of an oxygen sensor from a lower first voltage to a higher second voltage at a ramp rate. The ramp rate may be based on engine operating conditions.
