How to deal with oxygen sensor failure

The oxygen sensor just has a fault code, but it is only a surface poisoning, and it is very 

slight. If you replace the quality of the gasoline at this time, you can eliminate the toxic 

substances on the surface and make o2 sensor return to normal. Therefore, after the fault 

code appears, it is not necessary to replace the oxygen sensor. First, the fuel should be 

replaced. If the fault persists, replace the oxygen sensor.
