What is the reason for the low idle speed?

This may be caused by low engine temperature or damage to the throttle idle control valve. After this happens, read the fault code and check the throttle. Throttle is an important part of automobile engine, which is used to control the amount of air entering the engine.

The throttle valve is installed on the intake pipe of the automobile engine.

After the driver steps on the accelerator pedal, the throttle opening will increase, and the air entering the engine will increase.

After detecting the increase of air entering the engine, ecu will control the fuel supply system to increase the fuel injection quantity, thus increasing the engine speed.

When the engine is idling, the throttle will keep a small opening, and if the throttle is opened too much when idling, the engine will idle too high.

If the throttle is broken, just replace it with a new one.

If the idle speed increases because the engine temperature is too low, the idle speed will return to the normal level after the engine reaches the normal temperature.

The temperature is relatively low when the engine is started. At this time, increasing the idle speed can make the engine warm up quickly.

Every engine has a normal operating temperature range. Only in this temperature range, the engine has the highest efficiency and the lowest fuel consumption.
