Why does the idle high fan of the new Jetta keep turning?

The reason why the new Jetta idle high fan keeps running is that the throttle is dirty. Throttle: Throttle is a controllable valve to control the air entering the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It is connected with the air filter and the engine block. There are two kinds of throttle valves: traditional pull-wire type.

Throttle:

Throttle is a controllable valve to control the air entering the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It is connected with the air filter and the engine block. There are two kinds of throttle valves: traditional cable throttle valve and electronic throttle valve. The traditional engine throttle control mechanism works through a pull wire or a pull rod, one end of which is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate. The electronic throttle mainly uses the throttle position sensor to control the throttle opening according to the energy required by the engine, so as to adjust the intake air.

Throttle cleaning:

Unplug the wire harness plug next to the throttle, unscrew the fixing screw with a hexagon screwdriver, and then remove the throttle. Spray the detergent on the dirt. Try not to spray the cleaning agent on the outside of the throttle, and don't break the inside of the throttle forcibly, so as not to damage the nearby throttle motor.

Is the idle speed of the new Jetta 800 to 900 normal?

The idle speed of the new Jetta is abnormal at 800-900, and the idle speed of Volkswagen's new Jetta is usually around 700-800 rpm.

Introduction of automobile idle speed;

Idle speed refers to a working state. The idle speed of the engine is called idle speed, that is, the gear of the car is neutral. The engine speed at idle speed is called idle speed. You can adjust the idle speed by adjusting the throttle. Idle speed means that the engine "works without output".

Introduction of idle state of automobile;

When the engine is running, if the accelerator pedal is completely released, the engine will idle. When adjusting the idle speed, the speed should not suddenly rise or fall, otherwise it will cause early wear and tear to the engine, so it is best to go to the automobile maintenance department for adjustment. When the car stops and the engine starts, the lowest speed of the engine is called parking idle speed (when the engine reaches the normal working temperature, the process from cold idle speed to idle speed is called warming-up or warming-up).
