The car won't start after cleaning the throttle.

Check the working parameters of the parts on the throttle body. At the same time, pay attention to turn on the ignition switch. Generally, the opening of the throttle position sensor is between 17 ~ 19%, and the voltage is between 0.85 ~ 0.95V After the engine is started, the idle speed will definitely be high! If you need to clean the accelerator, you may encounter the problem that the car will not start. Therefore, the following points should be noted: 1. If there is too much sludge in the accelerator, it may lead to poor engine acceleration and increased fuel consumption. At this time, you can clean it, and then go to the 4S shop to get it done quickly. If you decide to clean it yourself, don't forget to initialize it. 2. When cleaning the throttle, first disassemble the intake pipe to expose the throttle, then disassemble the negative electrode of the battery, turn off the ignition switch and straighten the throttle plate. Next, spray a small amount of "carburetor cleaner" into the accelerator, and then carefully scrub it with polyester rag or high-spinning "non-woven fabric". Where the throttle can't reach, you can scrub it carefully with a clip. 3. After cleaning, the throttle must be initialized after installation according to the disassembly steps just now. Because the computer adjusts the throttle opening, it has a memory function. Due to the previous sludge blockage, the computer will automatically adjust the throttle opening to keep the air intake in a normal state. 4. If there is no sludge blockage after cleaning, but the throttle valve still keeps the previous opening, then the air intake will be too large. This will cause the engine to shake when starting, and the acceleration is weak, and the engine fault light may light up. It should be noted that sometimes the engine can work normally without initialization after cleaning the throttle valve, because the throttle valve is not too dirty, and its intake volume does not change much after cleaning.
