What does it mean if my check engine light comes on?

If your check engine light comes on it will either blink or remain still. Either way, it means there is an engine malfunction and your car needs to be checked.

  • If the light remains still that means that the problem is not an emergency but should be check as soon as possible.
  • If the light is blinking that usually indicates a severe issue with the engine. In this case you should pull over and get your car checked immediately. This usually indicates low oil pressure or overheating which could be extremely dangerous if you continue to drive.

What do I do if my check engine light comes on?

The most important thing to do if your check engine light comes on is bring in your car to get diagnosed.
