The dreaded check engine light often leads to calls asking, “What does a flashing check engine light mean?” A check engine light can be the sign of a variety of issues, some of which are a quick fix while others are more complicated repairs. Lets explore more about what this warning means for drivers in Chicago Heights in this quick check engine light breakdown.

What is a Check Engine Light?

The check engine light was standardized back in 1996 with a formal system of diagnostic trouble codes. This code system allows local service centers to diagnose your vehicle quickly and easily. You can also take the DIY approach and purchase your own code reader, but once diagnosed you will still need to schedule the appropriate repairs.

What Does a Flashing Check Engine Light Mean?

The check engine light notification can take two forms: a steady glow or a flashing light. Both indicate a problem with your vehicle that requires a trip to a Homewood service center, but if you see the flashing light you need to get your vehicle in as soon as possible.

  • Flashing Light: Signals more serious issues like engine misfire and should be brought in right away
  • Steady Glow: Still requires immediate attention, but not the same level of urgency.

Common Causes for a Check Engine Light

A check engine light can be caused by an array of issues, such as:

  • Loose gas cap
  • Emissions system issues
  • Faulty catalytic converter
  • Errors with the airflow sensor
  • Faulty spark plug wires

These are all common issues that can be quickly addressed by a qualified Chevrolet technician. One quick tip before calling a professional is to make sure it is, in fact, your check engine light that is on. One simple mistake drivers sometimes make is to confuse their “service required” light — which indicates a standard need for maintenance, such as an oil change — with the “check engine” light.
