[DIY] Lao Lang’s cleaning and repairing the oxygen sensor before repairing
JaneMacAdam 
11 The wolf in 2010 has been nine years old, in the sixth year of the annual inspection, because of the exhaust gas, has been dealt with, and then learned the lesson, he also took a series of measures, effectively passed the annual inspection. Just after this year’s annual inspection, I changed the former oxygen sensor, and then changed it back. Suddenly I thought, can the cutting-edge sensor be repaired? Checked the relevant posts, found that it can be cleaned, smooth purchase, and then start work on the weekend.
The position of the front oxygen sensor, the general car has two sensors, namely, the front oxygen sensor is the rear oxygen sensor, in which the front oxygen sensor is behind the exhaust pipe and in front of the ternary, which is used to detect the feedback combustion. The post-oxygen sensor is behind the ternary, which is used to detect the ternary working efficiency. This time it is aimed at the pre-oxygen sensor in the picture.
You can see that there are obvious scratches, this is the sixth year of the annual inspection, scalpers improper handling, due to a long time not loose, forced treatment caused by, distressed ah, so the car can not be dealt with by others.
The front oxygen sensor interface is this orange-red, clasp design, a press a buckle out, very simple.
As you can see, it’s very simple. You can do it yourself and release the interface.
Then use a large movable wrench to loosen, it has not been loosened for a long time, you can spray WD40 or loosening agent at the interface, do not force.
Smooth screw out, you can see that the complete loss of metallic color, has been gray, it is estimated that the work efficiency is not very good.
Take a closer look, a layer of dirt on the metal is covered, after all, too long, 9 years.

Prepare cleaning tools and cut 2 transparent bottles to hold detergents.
Clean the bottle to ensure the cleaning effect.
There are two kinds of cleaning agents: one is oxygen sensor cleaning agent, the other is corrosion inhibitor.
The oxygen sensor was yellow and irritating, so I didn’t dare to put it at home and put it in the corner outside the door. Only a few days later, it got moldy in this rainy weather, .
Just throw in the oxygen sensor before soaking.
I soaked to the top of my head, not too much, after all, the job is that part.
As soon as you throw it in, it reacts, it starts to bubble, and the dirt begins to soak out.

After a while, the color changed and turned into green.

Soak for more than ten minutes and brush with a discarded toothbrush to ensure the soaking effect.
You can see that it is really dirty, not just dirty.

In fact, it should be soaked again, the first time is too dirty, soak a few more times. But eager to deal with it.
Corrosion inhibitor is to deal with the residual cleaning agent and form a protective layer at the same time.
You can see a lot of diluted detergents.
Change the corrosion inhibition cleaning agent twice, and finally soak it clean.

Because after doing a good job to install in the car, the oxygen sensor must be kept dry, otherwise the high temperature will lead to fragmentation, must be guaranteed to dry, can only be served by the hair dryer.
Finally, take a look at the effect, compared with before, much better, the metal color has been exposed, the surface cover has fallen off, the effect looks good.

After cleaning and fully drying, it can be installed on the car in turn. 9 years is too long. I think the normal use of 20-30,000 kilometers should be cleaned once and form the good habit of regular cleaning in the future.
