Abstract
The present disclosure relates to a device and a method for removing a carbon from an oxygen sensor. The device may include an oxygen sensor installed in a gas exhaust line of a vehicle to measure an oxygen content in an exhaust gas, a valve for transferring a high-pressure air flow to the oxygen sensor, a valve actuator for driving the valve, and a controller for controlling the valve actuator to open the valve when an abnormality occurs in the oxygen sensor. When the abnormality has occurred in the oxygen sensor, the valve for transferring the high-pressure air flow is opened, and a temperature of zirconia provided in the oxygen sensor is raised to remove a carbon deposited on the oxygen sensor.
