Check Engine Light On? Here's Why You Should Address It Right Away

| By: Christian Brothers Automotive

Spotting a check engine light while driving can be alarming. However, it's crucial not to ignore this warning as it often signals a vehicle issue that needs immediate attention – and neglecting it may cause severe, expensive problems later.

Christian Brothers Automotive Spring Klein (Stuebner) is here to guide you on the importance of promptly addressing a check engine light, its potential causes, and how to manage the situation!

Why You Shouldn't Ignore a Check Engine Light

Ignoring a check engine light may seem like the easiest solution, especially if your vehicle seems to be running fine. However, there are several reasons why this is not a good idea:

  • Prevents Further Vehicle Damage: Ignoring the light could lead to more serious problems. The check engine light is your vehicle's way of telling you something is off. It could be a minor issue now that, if left unchecked, can evolve into a major problem causing extensive damage.
  • Saves You Money: Addressing the issue early can save you from costly repairs in the future. The longer an issue persists, the more likely it is to cause other components in your vehicle to fail.
  • Ensures Fuel Efficiency: A lit check engine light might indicate a problem with your vehicle's fuel system. Resolving the issue quickly could return your vehicle to its peak fuel efficiency, saving you money at the pump.
  • Keeps You Safe: Some issues signaled by a check engine light can be safety hazards - such as brake system failures. Prompt attention ensures your vehicle is safe to drive, protecting you and your passengers.
  • Preserves Vehicle Value: Keeping your vehicle in good working condition helps maintain its resale value. Future buyers or dealers will likely give a better price for a well-maintained vehicle compared to one with ongoing unresolved issues.

Even if your check engine light is on and your car is driving fine, don't wait to get it checked out by a professional. Ignoring the light can lead to bigger problems and more expensive repairs in the future!

What to Do When Check Engine Light Comes On

When the check engine light comes on, it's natural to feel a hint of anxiety. But fear not! By following a few simple steps, you can navigate this situation with ease and minimal stress. Here's what you need to do:

  1. Remain Calm: Firstly, don't panic. While the appearance of the check engine light indicates a potential issue, it might not necessarily mean a serious problem. Stay calm and focused.
  2. Check Your Dashboard for Other Warning Signs: A check engine light accompanied by other warning lights or changes in the vehicle's performance could indicate a more serious problem.
  3. Review Your Vehicle’s User Manual: The manual may provide information about the possible reasons for the light and offer initial guidance.
  4. Check Your Gas Cap: A loose gas cap can sometimes trigger the check engine light. If it's loose, tighten it and see if the light goes off after a few drives.
  5. Reduce Your Speed and Load: If you're towing something or driving at high speeds, slow down. Overexertion can exacerbate potential problems.
  6. Seek Professional Help: If the light doesn’t go off or if it's blinking, this is a strong signal you should visit a professional auto repair shop immediately.

Taking these steps can help you effectively handle a check engine light and ensure the safety of your vehicle. Don't delay in addressing this issue for a smoother and more enjoyable driving experience! Remember, our team at Christian Brothers Automotive Spring Klein (Stuebner) is always here to help with any car troubles you may have.

Potential Causes of a Check Engine Light

Your check engine light could come on due to a variety of reasons. Here are some of the most common causes:

  • Faulty Oxygen Sensor: The oxygen sensor measures the amount of unburnt oxygen in your vehicle's exhaust system. If faulty, it could lead to lower fuel efficiency and damage to your catalytic converter.
  • Loose or Broken Gas Cap: As simple as it sounds, a loose or broken gas cap can allow fuel vapors to escape, lowering your car's fuel efficiency and causing the check engine light to illuminate.
  • Bad Spark Plugs or Wires: Spark plugs ignite the air/fuel mixture in the combustion chamber of your vehicle while the wires deliver the spark from the ignition coil to the plugs. If either is faulty, your engine may experience misfires, reduced power, and less fuel efficiency.
  • Malfunctioning Mass Airflow Sensor: This sensor measures the amount of air entering the engine to determine how much fuel is needed for efficient operation. A faulty sensor can lead to damage to the spark plugs, oxygen sensors, and even the catalytic converter.
  • Failing Catalytic Converter: The catalytic converter helps protect our environment by converting harmful carbon monoxide into carbon dioxide. Damage to this component can cause reduced performance and fuel efficiency, and the vehicle might not pass an emission test.

While these are common issues, there are numerous reasons why your check engine light might come on. It's always best to seek help from a professional, such as Christian Brothers Automotive Spring Klein (Stuebner), to accurately diagnose and resolve the issue.
