The engine light, also known as the check engine light, is a warning signal that appears on the dashboard of your car. When this light turns on, it indicates that there is a problem with your vehicle's engine or emission control system. You should have the car serviced as soon as possible to prevent any further damage to the engine or other parts of the car. Ignoring the engine light can cause costly repairs in the long run. A professional mechanic can use a diagnostic tool to determine the exact issue causing the light to turn on and fix it efficiently. If the light is flashing, it signifies a severe issue that requires immediate attention.
