After cleaning the accelerator,

Manually restore the factory settings, that is, initialization. If the initialization fails, it is enough to set it several times, but not all models can be set manually. If you can't set it manually, use a computer to match it. Cleaning the throttle is very common. Basically, it can be cleaned every 30 thousand kilometers. In fact, the owner knows the relevant methods and steps and can clean it himself.

How to restore manually

According to different models, the recycling methods are different. For example, after the throttle valves of American cars and Japanese cars are cleaned, the battery negative electrode can be disconnected for more than 1 minute before initialization. Or after cleaning, take out the EFI and ETCS fuses in the fuse relay box and put them back 1 min. However, this method has a disadvantage, that is, it is troublesome to reset the parameters such as windows, skylights and interior time after the battery is turned on and off.

How to match with the computer

In fact, many diagnostic instruments can match the throttle now, and the matching method is also very simple. As shown in the figure below, you can match by selecting the idle reading reset in the special function. Matching with the diagnostic instrument is a process of computer re-memorization, because the throttle opening before cleaning is relatively large, and it becomes smaller after cleaning. The throttle opening data stored in the engine ECU program before cleaning is still not available and needs to be reset.

Why did the game fail?

In fact, in the process of throttle initialization, several conditions need to be met, such as the engine water temperature should be above 80 degrees, the throttle should be in the idle position, the ignition switch should be in the "on" position, and the battery voltage should not be lower than 12 volts. If the matching fails, it may be because the throttle valve has a fault code, so it is necessary to check whether the lower intake pipe is leaking, blocked or stuck. If it fails again, replace it with another diagnostic instrument for matching.

To sum up, if you manually restore the factory settings to increase fuel consumption, you can use diagnostic methods to match. If the matching fails, you need to check the relevant reasons.
