The check engine light is a warning that there is an urgent issue with the car, even if it is not the end of the world when it does so. When this light displays, what does it mean? When the check engine light appears, whether it be flickering or constant, the computer in your automobile assumes there is a malfunction that is endangering the emissions control system. Now, the issue’s severity and the harm it causes might range widely. However, this type of damage has to be handled by a competent car repair shop worker since no matter the situation, any issue with your engine will not get better and will only worsen. Following a detailed explanation of the differences between a constant check engine light and a flashing check engine light, we’ll discuss the five most typical causes of this problem.


  • Consistent Light – If your check engine light is on continuously, your engine has a problem. It is not something that must be taken care of with your next paycheck, but it must be taken care of if you intend to keep your automobile for a longer amount of time. The check engine light often indicates a loose gas cap and can typically be remedied at home. However, if this does not resolve the issue, we firmly urge that you get the automobile inspected by a qualified technician.
  • Flashing light – On the other hand, if you see a flashing light, you must stop right away since your car is experiencing a significant problem that might seriously harm the engine. The most typical reason of a flashing light is an engine that is misfiring. Since these issues are frequently more difficult, it’s critical to get your car in the hands of a mechanic right away. As soon as this light starts to flash, do not try to drive.


  • The oxygen sensors needs a replacement
    • The oxygen sensor measures oxygen in the exhaust to inject the proper amount of fuel to the engine. If there is a problem here, it could cause your vehicle to lose up to 40% off its mpg.
  • The Gas cap is loose or damaged
    • Your gas cap covers the gas tank. It also works to prevent harmful chemicals getting into the environment.
  • The catalytic converter is damaged
    • The catalytic converter protects our environment by converting harmful carbon monoxide into carbon dioxide. Problems arise here due to lack of maintenance.
  • Issue With The Mass Airflow Sensor
    • This sensor measures the amount of air entering the engine to determine how to run your engine efficiently.
  • Spark plugs and wires gone bad
    • The spark plugs on a vehicle work to ignite the gas in the combustion chamber of your vehicle while the spark plug wires deliver the spark from the ignition coil to the spark plugs.
