Cleaning skills of throttle valve

Check and maintain your car regularly. Spark plug carbon deposit, throttle carbon deposit and high-voltage line leakage will all cause abnormal ignition and increase fuel consumption. You will encounter these problems when driving at a low speed in the city for a long time, so you should check and maintain the car regularly.

Too much carbon deposit in the throttle of automobile engine may cause poor engine acceleration and increase fuel consumption, which is a big worry for car owners. So what should I do if the throttle is dirty?

In fact, as long as you clean the throttle, you can get it quickly in the 4s shop, but you don't have to go to the 4S shop every time you clean it. Actually, you don't have to. The owner can get it himself, just don't forget to initialize it.

When cleaning the throttle valve, first remove the intake throat to expose the throttle valve, remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, spray a small amount of "throttle cleaner" into the throttle valve, and then carefully scrub it with a polyester rag or a high-spin "non-woven fabric". Deep in the throttle, you can hold the rag and scrub it carefully where your hands can't reach it.

After cleaning, follow the disassembly procedure just now, and then start the initialization of the throttle valve after installation. After cleaning the throttle, it needs to be initialized, because the computer has a memory function when adjusting the throttle opening, and because there was sludge blockage before, in order to ensure air intake, the computer will automatically adjust the throttle opening to make the air intake in a normal state.

But there is no sludge blockage after cleaning. If the throttle valve still maintains its previous opening, it will cause excessive intake air. As a result, the engine will shake when starting, and the acceleration will be weak, and the engine fault light may light up.

Then why does the engine sometimes work normally without initialization after clearing the throttle? That's because the throttle is not too dirty, and its intake has not changed much after cleaning. However, the change of the throttle valve after cleaning is invisible to the naked eye and needs to be initialized.

In fact, initialization is very simple. You can do it with a special computer or by hand, but it is not as fast as a computer, and sometimes it will fail. It doesn't matter if you fail. Do it again. According to different cars, there are two ways to initialize:

1. Turn the key to the second gear, which is the gear indicated by the instrument. Then wait for 20 seconds, press the accelerator to the bottom, hold it for about 10 second, release the accelerator, turn off the ignition switch, pull out the key, and the initialization is complete.

2. Turn on the key in the second gear for 30 seconds, then turn off the ignition switch and pull out the key. It should be noted that after the two methods are completed, it will take some time to try to ignite. Generally, you can wait 15-20 seconds, and then ignite to see if the refueling is normal and the engine fault light is off. If at first you don't succeed, you can do it again until you succeed. You can usually succeed once, at most twice.
