What is the reason for the engine fault light coming on and then turning off after restarting?
1 Answers
The engine fault light coming on and then turning off after restarting is part of the self-check process when starting the vehicle. This phenomenon is normal and there is no need to worry. During the use of motor vehicles, it is important to always pay attention to whether the dashboard still shows any fault lights. If a fault light appears, a dedicated diagnostic computer can be used to detect the problem for repair. Below are some related extended information about the engine fault light: 1. The engine fault light detects whether the exhaust emissions are normal through sensors. If the emissions exceed the standard, the engine warning light will come on. In most cases, if the light comes on and then turns off after restarting, it indicates that there is no problem with the vehicle. 2. The reason is likely that some issues occurred due to poor atomization in the fuel engine cylinders just after starting the vehicle, causing the engine to alert. When the temperature rises, the warning light will naturally turn off.
