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.


Can the oxygen sensor be broken if it is broken? Our suggestion is that it is best not to open. 


Normally, the oxygen sensor is faulty or broken, and it will not have much impact on the 


operation of the vehicle in a short period of time, but what you need to know is that if you 


continue to open it, it will often be associated with it. Other faults occur, such as carbon 


deposits, three-way catalytic plugging, engine noise, and the like. If you don't want to pay for 


these problems, it is best to go for repair or replacement as soon as possible.Don't ignore your 


safety in order to save a little money.
