Abstract: PURPOSE: A method is provided to control a heating feedback of an oxygen sensor according to internal pressure for a predetermined time period by measuring voltage of the oxygen sensor. CONSTITUTION: Internal pressure of an oxygen sensor is measured for a first predetermined time. A heater driving control signal is outputted based on an internal pressure value of the oxygen sensor. When the first predetermined time lapses, output voltage of the oxygen sensor is measured in order to generate a feedback control signal. If internal pressure of the oxygen sensor is below a predetermined reference value, a first heater voltage duty control signal is outputted so as to increase a heater voltage duty(S170). If internal pressure of the oxygen sensor exceeds the predetermined reference value, a second heater voltage duty control signal is outputted so as to reduce the heater voltage duty(S171).
