The process and matters needing attention of experts cleaning throttle valve by themselves.

In the process of automobile maintenance, the maintenance personnel in the repair shop or 4s shop often recommend the item of cleaning the throttle. Needless to say, the function of cleaning the throttle valve has been said by the service staff in the store for countless times. It is very effective to clean the throttle under certain faults, such as poor parking and high idle speed, but the cost of cleaning the throttle in the repair shop is not low, not to mention the 4s shop. In fact, it is also a very simple thing to clean the throttle yourself. Just pay attention to some matters.

Cars are mostly electronic throttles, so it is best to turn off the car key door or cooperate with two people (someone is responsible for stepping on the throttle) before cleaning the throttle. Before removing the throttle, it is best to clean the engine compartment briefly and remove the engine cover. Prepare a screwdriver (more convenient) or sleeve ratchet (depending on personal situation), a clean cotton cloth and a bottle of detergent. Among them, the purchase of detergent will generally not exceed that of 20 yuan, and you can start by preparing these.

1. Remove the intake pipe from the throttle, generally unscrew the clamp at the intake pipe and pull it out. Pay attention to nearby clamps or small pipes during operation. Don't damage other parts because of excessive force, especially pay attention to nearby vacuum pipes (thinner).

2. According to the effect, cleaning the throttle is the best, but it is more troublesome to disassemble and clean the throttle, and the effect is similar to that of direct cleaning, so most repair shops do not need to disassemble and clean it. At this time, you can see a black substance on the edge of the throttle. Our purpose is to remove this substance that affects the throttle opening and make it clear that it will restore the throttle opening to its original level.

We use two people to work, open the key door, and one person is responsible for stepping on the accelerator. At this time, you can fully open the throttle for cleaning.

4. Spray the detergent on cotton cloth to clean the inside of the throttle, or spray it into the throttle, but the amount should not be too large, and try not to spray it on the throttle shaft. Then wipe the throttle repeatedly.

5. The effect after cleaning is very obvious, and the inner wall and throttle are very clean, achieving the cleaning effect. After that, it is reloading work. Don't neglect the reassembly work, and don't miss the wrong parts. Especially when installing the throttle pipe, it must be in place to avoid air leakage, and the plug that needs to be unplugged must be plugged in.

6. The last step is to match the throttle valve. According to different models, the matching method of throttle is different. Generally speaking, you only need to disconnect the power storage. Note that it is best to check the matching method of the vehicle type before matching. Some models can't be powered off, otherwise it will be more troublesome to trigger anti-theft. These cars need computer matching. There are also some cars that will open the key door and automatically match. After the matching is completed, there will be no impact on the car.

After idling for a period of time, the idling speed tends to be flat, and the project of cleaning the throttle valve has been completed. In fact, cleaning the throttle is very practical for most economical car owners, and it will increase the fun of using the car. Why not? Generally speaking, tools and consumables for cleaning the throttle are common and cheap. Doing it yourself will increase the fun, save the cost of car use, and at the same time learn more about cars.
