What Does Check-Engine Light Mean?

There are a few important things to keep in mind if you are certain that the check-engine warning light that is shining back at you from the gauge cluster is one.

  • You don’t have to come to a complete stop right away if the light is a steady orange or yellow and there is no discernible change in the way the car is driving. It’s possible that the issue is minor, but as we’ve already mentioned, it wouldn’t be a good idea to wait until the car starts to exhibit obvious problems before addressing it. A loose gas cap is occasionally the culprit.
  • However, if the warning light does ever begin to flash, stop and pull over. This almost always denotes a significant issue, and driving the vehicle further could result in significant harm.

In the event that your instrument cluster displays the more typical solid amber or yellow check-engine warning, there is an accessible tool that can assist you in understanding what is going on long before you visit a repair facility or dealership. That’s because every car produced beginning with the 1996 model year speaks the same fundamental language, and understanding it costs much less time and money than you might think.
