Do not forget to initialize after car throttle cleaning

If the throttle sludge is too much, it may cause the engine to accelerate and the fuel consumption increases. This is a major annoyance for the owners. What should be done if the throttle is dirty? Cleaning is done, go to the 4S shop can be done quickly, but not every cleaning must go to the 4S shop? In fact, you don't need to, you can get it yourself, just don't forget to initialize it.

When cleaning the throttle, first remove the intake pipe, expose the throttle, remove the negative pole of the battery, close the ignition switch, straighten the throttle flap, spray a small amount of “carburetor cleaning agent” into the throttle valve and use Polyester wipes or high-spun "non-woven fabrics" are carefully scrubbed. Deep in the throttle, places where the hands are out of reach can be carefully scrubbed with a clamped rag.

After the cleaning is completed, follow the procedure just disassembled. After the installation, the initialization of the throttle is started. After the throttle is cleaned, initialization is necessary because when the computer adjusts the throttle opening, it has a memory function because There is mud clogging, in order to ensure the intake air, the computer will automatically adjust the throttle opening, so that the air intake is in a normal state.

After cleaning, there is no blockage of the sludge. If the throttle valve still maintains the previous opening, then the intake air volume will be too large. The consequence is that the engine will start to shake and the engine will fail to accelerate. The engine fault light may also be spotted. bright.

Why does it sometimes work without initializing the engine after cleaning the throttle? That's because the throttle isn't too dirty. After cleaning, its intake hasn't changed much. However, the change in the throttle after cleaning cannot be observed with the naked eye, so initialization should be done.

In fact, the initialization is very simple, can be done through a dedicated computer, the same can be done manually, but not as fast as the computer to do manually, and sometimes fail, failure does not matter ah, do it again on the line. There are two ways to do initialization depending on the car:

The first is the second key to open the key, that is, the instrument indicates that the bright one, and then wait for 20 seconds, step on the accelerator in the end, hold about 10 seconds, loose the throttle, turn off the ignition switch, pull out the key, initialization finished.

The second is to turn on the second gear and keep it for 30 seconds. Then turn off the ignition and remove the key. It should be noted that after the two methods are completed, they must wait for a period of time before they can try to light the fire. Generally, wait for 15-20 seconds, and then light up to see if the fuel is normal and whether the engine fault light is off. If it is unsuccessful, it will be done a second time until it is successful. Generally, it can be successful once, at most twice.

However, depending on the car, the method of restoration is not the same. The bear manager of Guangben said that some cars must be initialized through a computer. If that is the case, it is recommended that the owner deliver the car to a professional device. Shop to clean.
