Why is a Check Engine Light Diagnosis Important?

Your vehicle provides key information in its dashboard lights. If your check engine light is on, engine diagnostic services can be a useful tool in determining why.

There are several possible reasons for an illuminated or flashing check engine light, including the need for regular maintenance, such as an oil change, or because there may be an issue with your braking, electrical, or vehicle computer performance.

How Often Should I Get a Car Diagnostic Test?

If the check engine light is illuminated, you should bring your vehicle in as soon as possible.

For optimal vehicle safety and reliability, diagnostic checks should be a part of your routine vehicle maintenance, even if your check engine light isn’t on or flashing.

The best adventures are the ones that don’t involve unplanned pit stops to have your car repaired.

Why choose a Goodyear Auto Service location when your Check Engine Light is on?

Without a state-of the-art diagnostic tool like the ones our certified technicians use to pull and read your vehicle computer’s trouble codes, critical problems can go unnoticed, even by an experienced mechanic.

We’ll take the time to explain your vehicle’s codes and what they mean so you can make confident, informed decisions about what your car needs.


When illuminated, your check engine light will either blink (for serious problems) or remain constant (for less serious problems). Either way, you should have the vehicle checked by a qualified professional as soon as possible. Learn more at our Dashboard Light Explanation page.
