What's the difference between idle speed of vehicles? The hazards of high idle speed are increasing fuel consumption, increasing engine working temperature and increasing machine wear. The hazard of low idle speed is that it is easy to turn off when starting. If it is started frequently, it is not good for the engine and starter. In addition, if the idle speed is too low, it is very likely that the vehicle will turn off when driving, which is very dangerous. It is easy to accumulate carbon in the engine cylinder for a long time, which leads to weak acceleration.

The common reasons for the high idle speed of the car are that the throttle is stuck and closed loosely; Idle speed control valve failure; Water temperature sensor failure; Air leakage in the air intake system; Air conditioning switch and power steering gear pressure switch are faulty.

Extended data:

Chery Tiggo 3 idle speed is introduced as follows:

The normal idle speed of EFI engine is determined by idle speed control valve. According to the engine speed, temperature, throttle switch, air conditioning switch and other signals, the electronic control unit will increase the intake bypass passage of the idle speed control valve or directly increase the throttle opening after calculation, thus increasing the air intake and improving the engine idle speed.

If there is oil pollution and carbon deposition, the idle speed control valve will jam or the throttle valve will not close normally, which will make the electronic control unit unable to adjust the engine idle speed accurately. Check the action sound of idle speed control valve. If there is no action sound, the idle speed control valve is faulty.
