APPARATUS AND METHOD FOR CONTROLLING OXYGEN SENSOR

摘要

An apparatus for controlling an oxygen sensor may include an oxygen sensor configured to measure the exhaust gas which is generated by the combustion of the engine to generate an oxygen signal, and a controller configured to detect, through the oxygen sensor, a lag of the oxygen signal having responsiveness which is reduced depending on an oxygen amount of the exhaust gas, store information on occurrence factors which cause the lag of the oxygen signal, and increase a current heating quantity of a corresponding specific region about the occurrence factors to reconfirm whether the oxygen signal lags and determine the oxygen sensor as a failure or release a failure detection for the oxygen sensor.
