PROBLEM TO BE SOLVED: To provide a voltage detection compensation device for an oxygen sensor which allows a user and a maintenance supplier to control an air-fuel ratio of an engine depending on a particular situation to respond to various requests. SOLUTION: A voltage detection unit 10 has a control unit 20. The voltage detection unit 10 detects a feedback voltage of the oxygen sensor 06. The control unit 20 provides compensation to the feedback voltage of the oxygen sensor 06 by a voltage control means. The voltage control means in this structure can be both manually and automatically controlled. By this, when an abnormality occurs in the feedback voltage of the oxygen sensor, the abnormality is detected and corrected by a detection compensation device, thereby keeping the air-fuel ratio of the engine normal, controlling environmental pollution, and obtaining a structure considering environmental preservation and energy saving and having both practicality and progressivity.
