Check Engine Light: Flashing vs. Solid

Your vehicle is equipped with one thing that can save you from headaches and costly repairs. That is the check engine light. It comes on when something is wrong with one or more of the vital systems in your car. Despite its name, it also comes on if there are problems with the transmission, sensors, starter, cooling, and more. One thing a lot of people don't know is that the check engine light can be solid or flashing. Here are the main differences.

Solid Check Engine Light

When the check engine light turns on and is solid, it usually means there is something wrong, but it isn't urgent. But, don't confuse non-urgent with not important. The light informs you of a problem, which should be checked when possible at a repair shop. It can turn on because of a faulty sensor giving incorrect information or a problem with the spark plugs. The car can still function with these problems, but not for long because they can evolve into much more complex ones.

Flashing Check Engine Light

If you notice a flashing check engine light, you are in big trouble. This is much more serious than a normal, solid check engine light. The point of its flashing is to catch your attention because something important is having problems. Courses can vary from misfiring to crankshaft damage, but all of them signal that it's too late for a quick repair. 

What Happens If You Ignore Them?

When talking about a solid check engine light, ignoring it can cause further problems, resulting in it starting to flash. Make sure to take notice of the check engine light as soon as you can. Here are some of the things that can happen if the check engine light is ignored for a long time:

  • Transmission failure
  • Blown engine
  • Not being able to stop
  • Wheel and tire damage
