Abstract
A method for controlling an oxygen concentration sensor for controlling an internal combustion engine, having a sensor body including a wall of oxygen ion conductive solid electrolyte member, and a heater element for heating the wall of oxygen ion conductive solid electrolyte member. During a time period after the ignition switch of the internal combustion engine is turned on, current value of the heater current to the heater element is reduced to a value which is smaller than the current value of the heater current to be supplied after the lapse of the time period.
