ABSTRACT:
An air-fuel ratio sensor early activation feedback system and method includes an air-fuel ratio sensor for measuring an air-fuel ratio in an exhaust gas generated by an internal combustion engine and a heater for heating the air-fuel ratio sensor. A controller activates the heater prior to startup of the engine based on prior startup times for the engine.
