The correct way to clean the electronic throttle is

Clean the electronic throttle, and directly spray the throttle cleaner on the wiping cloth to scrub the throttle. The whole process is relatively simple and easy to operate without disassembling the throttle assembly. But everything has two sides, and the cleaning effect of this method is relatively general, which is only applicable to the throttle that is not particularly dirty. If your throttle is dirty and there are a lot of dirty things, it is best to clean it by disassembling and washing.

After cleaning the throttle, you must use the detection computer to match the throttle data and reset the throttle opening, because the ECU of the car has memorized the opening when there is carbon deposit. If it is not reset, the engine will have unstable idle speed and high speed, which is even worse than before cleaning, so the owner had better not wash the throttle himself, and this part of the money can't be saved. After all, data matching can only be done with professional equipment.

Because of the ventilation function of engine crankcase and the function of activated carbon canister solenoid valve, a small amount of gasoline vapor will be brought to the throttle, and the oil and gasoline attached to the throttle will continue to attach to dust. How long the throttle will be dirty depends on the quality of air filter, engine oil, road conditions, temperature, engine working temperature, driving habits and so on. Dirty oil, long-term non-replacement of air filter and poor quality of air filter will aggravate the dirtiness of throttle valve, so this situation needs to be cleaned regularly.
