Check engine light

Our technicians regularly receive calls from worried customers who say, “My check engine light went on, what should I do?” While the very sight of that amber-colored light sends fear into the hearts of many Schaumburg and St Charles drivers, there’s no need to panic just yet. This warning sign indicates that your car needs a trip to the dealership, but the culprit could be as simple as a loose gas cap or a worn spark plug! Let’s take a look at some of the most common culprits behind the check engine light flashing, so you can get back on the road with total peace of mind.

Why is my Check Engine Light On?

Let’s start with the basics: what is the point of my check engine light anyway? This handy safety feature was introduced into vehicles to help alert drivers of issues under the hood that may not be immediately obvious. When the check engine light pops on as a result of a problem, your car also generates an engine diagnostic code. You can schedule a service at Biggers Mazda and a technician will look up the code, or you can even look it up yourself with a simple code reader from the auto parts store. The light won’t turn off until you resolve the underlying problem, so be sure to schedule your visit to the dealership promptly!

What are the Common Causes of Check Engine Light Flashing?

When your check engine light glows a steady amber, yellow, or orange glow, this indicates that you have a problem that needs to be addressed. Some of the most common issues include:

  • Catalytic converter problems
  • A loose gas cap
  • A blocked mass airflow sensor
  • An oxygen sensor malfunction
  • A worn spark plug

What if you notice your check engine light flashing? That’s a little different. This indicates that your car has an issue that must be investigated immediately. It might be an engine misfire or a fire hazard. Do not delay!
