Is the throttle leak reporting a fault?

Throttle leakage will report a fault. If the throttle leaks, the engine fault light will come on. When the throttle leaks, the idle speed of the engine is usually higher than the normal speed. We can see if it's the same. Looking at the data flow of the engine with a computer will also find that the intake pressure is also high.

Air leakage from the throttle will cause the engine to idle unsteadily, run fast, lack power, and occasionally stall after parking. The leaked part will make the hood black. Throttle air leakage is generally caused by air leakage between throttle seat and intake pipe interface seat. This interface is usually fixed with screws and clips, which can easily lead to air leakage if improperly installed.

Cleaning cycle of throttle valve:

The change of throttle usage mainly depends on air quality, air filter status, vehicle use environment, driver's driving habits and other factors, so it is impossible to simply judge the cycle of vehicle throttle cleaning by mileage.

When buying a vehicle, the interval between the first cleaning of the throttle must be the longest, and then the cleaning frequency will become more and more intensive with the factors such as crankcase ventilation and oil and gas condensation in the intake pipe. Generally, when driving, there will be situations such as unstable idle speed, oil truck and acceleration truck. Generally, it is caused by dirty throttle.
