What does a Check Engine Light Tell?

A check engine, as the name implies is a safety component connected to the engine, playing a major role in notifying you of the defects in the car. When a light ignites in your check engine, it is a warning signal that there is a fault in the emission system, engine, or any system connected to the car’s engine. Thus, when a car’s defect is related to the engine, the check engine light will ignite to notify the driver about the fault and take immediate action.

The check engine light ignites in different colors, too, indicating the severity of the fault. If the engine light ignites red, it denotes the defect is severe and has to be fixed immediately. And,  if the check engine light is lit yellow or orange, the severity of the faulty component is less, but it needs to be repaired and serviced. If blue or green ignites in the check engine light, the issue is mild in the car and implies the faulty system in the car is operating.
