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 engine light can be solid or flashing. Here are the main differences.

Check Engine Light Solid / What Does A Solid Check Engine Light Mean

Now that we answered your question, “What does a solid check engine light mean?” You know that if your check engine light solid, it often signals engine or emissions issues needing attention, and ignoring it can lead to costly repairs. If you see this, stop by ABCO Diesel for expert diagnostics to pinpoint the problem and ensure your diesel vehicle runs smoothly.

Solid Check Engine Light

When the 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.

Think of a solid check engine light like a yellow traffic signal—it’s caution, not calamity. It shows a detected issue, such as a loose cap or minor emission fault, that should be diagnosed with scanning tools soon. By contrast, a check engine light solid versus flashing is the difference between a caution light and a red alert—flashing signals engine misfire, a serious fault warranting immediate stop and diagnosis

Flashing Check Engine Light

If you notice a flashing 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
