The cleaning of the car's oxygen sensor is conducive to the maintenance of the car. There are also many owners who don't know how to clean the oxygen sensor of the car. Even if they go to the repair shop, they know that they need to be cleaned regularly. Therefore, the owners often clean the oxygen sensor and the various parts of the car. The following is a small series to introduce how to clean the oxygen sensor. Right~ Find the oxygen sensor and pull it out: This is the chemical used for cleaning, ferric chloride and oxalic acid. Put the front oxygen sensor inside the ferric chloride Soak for a while, take it out and wash it with water. Wash with oxalic acid, you can see a lot of dirty things washed down This is the oxygen sensor after cleaning, just like the new one. The bottom oxygen sensor is turned down and cleaned. This is a photo after soaking in ferric chloride. Soaking with oxalic acid This is the plug of the oxygen sensor. It is very strong and difficult to pull. I didn't take it down. I dangle it directly. I have 4 bricks underneath. This is a clean after oxygen sensor The specific methods are as follows: Item, special wrench: After observation, you can first disassemble the iron cover outside the three-way catalysis, and then use 22 wrench to reach inside and disassemble, the item has eyebrows. The second item, the lab teacher who found the School of Environmental Engineering, was not a question after inquiry. He also tutored the knowledge of chemistry. (The solution to be blended, 10% ferric chloride, 90% pure water + appropriate amount of hydrochloric acid) The function of hydrochloric acid is to convert iron cyanide and other substances (alkaline) on the surface of the oxygen sensor into ferric chloride, but if Direct use of diluted hydrochloric acid may burn out the sensor, so it is necessary to complete this process in the ferric chloride solution to play a protective role. Hydrochloric acid needs a little bit of addition, and it is better to test with a used spark plug. Looking at the methods and steps to clean the oxygen sensor, do the owners want to try it for themselves? After cleaning it, not only has a sense of accomplishment but also saves a lot of money. Regular cleaning of the oxygen sensor is good for car maintenance, there will be no failure, and repairing an oxygen sensor is also a lot of money, so some diligent car owners may wish to give it a try.
