Abstract
The gas sensor control apparatus is for controlling a gas sensor including a sensor element having a solid electrolyte layer, and first and second electrodes located on opposite sides of the solid electrolyte layer, the first electrode serving as a gas detecting electrode, the second electrode serving as a reference electrode, the sensor element generating, as a sensor output, a current flowing between the first and second electrodes having a value depending on concentration of a specific gas component contained in a gas under measurement. The gas sensor control apparatus includes a determination function of determining whether or not it is time for the gas sensor to start operation, and a control function of forcibly supplying oxygen from a side of the second electrode to a side of the first electrode on a temporary basis when a determination result of the first function becomes affirmative.
