How much does it cost to clean the throttle valve of Southeast DX3? How long does it take to clean the throttle valve of Southeast DX3?

southeastDX3In terms of cleaning the oil line throttle, it takes about 200-300Yuana single throttle valve costs 50-80 yuan, and it should be cleaned when it is generally controlled at about 20,000 kilometers.

The main function of the throttle is to control the amount of air intake according to the load of the engine.

As for how often to clean, it depends on many aspects. For example, the driving environment of the vehicle, the control method of the EFI engine, etc. If the vehicle operates in a relatively polluted environment (mainly referring to inhalable particulate matter), impurities will quickly accumulate on the throttle. Over time, it will affect the engine's air intake, and it needs to be cleaned. This phenomenon is most noticeable when starting the vehicle. For another example, some Japanese engine control systems traditionally like to calculate fuel injection and ignition timing by measuring air flow. Therefore, the requirements for the accuracy of air flow measurement are very strict. A slight blockage can also cause abnormal engine operation. But for some American engines, which do not use air flow as the basis for calculation, there will not be such a big response.

Therefore, different vehicles and different working environments will cause inconsistencies in the engine throttle valve cleaning time. There is no rule about how often you should clean the throttle valve. If there are such regulations, they are abnormal regulations and indicate that the car has a design defect. One thing that needs to be explained is that any vehicle that requires frequent cleaning of the throttle valve is a faulty vehicle. For some vehicles with electronically controlled throttles, you can contact the repair station to make adjustments through ECU software upgrades. If the problem cannot be solved after repeatedly cleaning the throttle valve at the service station, it is recommended to return the vehicle (generally impossible) or replace it.
