How many kilometers does Tiggo 3 throttle need to be cleaned?

There is no uniform regulation on how many kilometers to clean the throttle.

The frequency of cleaning the throttle valve depends on the use environment of the engine and the control mode of the electronically controlled engine.

The operating environment is poor and there are many pollution particles, so the cleaning frequency will be higher.

Japanese engines prefer to control fuel injection and ignition timing through the size of air flow. If the throttle valve is slightly dirty or blocked, it will cause the engine to work abnormally. American engines do not adopt this design concept.

Usually, a faulty car needs to clean the throttle frequently.
