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.
