What does it mean when the charging fault light comes on?

[VonRylee]

Generally, it is because the household socket is not grounded. Below is an introduction about the fault light: Reason: When the engine is burning, it requires air intake. In this process, the air filter is very important. If the car's air filter is not clean and not cleaned regularly, it will affect the car's air intake. Over time, it can easily become clogged, and in severe cases, it will cause the engine fault light to come on. Method: Check the injectors of each cylinder. Let the engine enter idle operation and disconnect each injector plug one by one to check whether the idle speed changes. If disconnecting each cylinder's injector causes the idle speed to decrease roughly the same, it means all injectors are working normally. When disconnecting a certain injector, if the engine idle speed and its stability do not change, then measure the resistance value of the injector plug to see if it is 10~13. If it does not meet the standard, replace the injector.
