What is the high idle speed of Guangqi Honda Odyssey?

Air intake system, fuel system and ignition system will all lead to excessive idle speed. In addition, water temperature, carbon canister purification, contact with catalytic lamp, etc. It will also cause excessive idle speed.

Solution to high idle speed of engine;

1. When the engine water temperature is low and the engine voltage is low, the electronic control unit shall be programmed to appropriately increase the idle speed. Under this normal condition, if the engine water temperature is normal, the idle speed is high, and there is no air opening adjustment, it means that there is something wrong with the system, whether it is an electronic control system or a mechanical system.

2. If the idle speed is too high due to mechanical failure, check whether the intake pipe leaks, whether the vacuum pipe falls off and whether the intake pipe is damaged (the intake pipe of Volkswagen engine is mostly rubber pipe). Because the air intake of the engine is very small at idle speed, if there is air leakage, the idle speed will be too high.

3. The leakage of fuel injector may lead to excessive fuel supply, which may lead to higher idle speed than normal.

4. For EFI vehicles equipped with fuel vapor recovery system, fuel vapor should not enter the intake pipe at idle speed. If fuel vapor is sucked into the intake pipe at idle speed due to system failure, the idle speed is higher than normal.

5. After cleaning the throttle body and idle speed control valve, the idle speed may be high after starting, which is a learning process for the computer, because in the past, the engine idle speed will drop after the throttle body and idle speed control valve are dirty. In order to stabilize the idle speed, the electronic control unit will control the opening of the idle speed control valve or throttle valve to increase the intake air, thus stabilizing the idle speed. After cleaning, the ECU also controls the air intake according to the original opening, and the engine idle speed will increase.
