Check Engine Light DiagnosticWhat Does it Mean if my Check Engine Light is On?

As drivers, we have all had that “uh-oh” moment of the dashboard check engine light turning on. There are many reasons why this indicator lights up. Some reasons are minor and others can point to more concerning problems. If yours ignites, call your certified auto mechanics of Carolina Auto Service in Winston-Salem to schedule diagnostic service. As part of this important service, we will find out why your light is steadily lit or flashing and explain the care your vehicle needs.

What Does My Engine Light Mean?

There is no one easy answer to this question, “What does my check engine light mean?” To find the answer, your certified auto mechanic must perform diagnostic service.

However, we can explore the circumstances typical to this warning light turning on. These scenarios include:

Conditional Lighting or Haphazardly Blinking

If your warning light only turns on during certain circumstances, this can point to a mechanical issue related to those types of situations. If your light is inconsistently blinking but stops doing so, this indicates an engine problem that comes and goes. You should never put off visiting Carolina Auto Service in these circumstances. We can provide quick diagnostic service and an auto repair plan to get your vehicle back in top running form.

Steadily Lit

If your check engine light turns on and remains lit despite no detectible problems, you likely have an issue in your vehicle’s emission control system. In this case, your vehicle will only run in lower gears. That change occurs at the command of your car’s computer to protect the engine. In this case, you need to schedule diagnostic service at Carolina Auto Service immediately.

You Can Sense Some Performance Issues with a Steady Light
Another possible scenario is the check engine light is steadily lit and you notice problems with how your vehicle runs. In this case, you probably have an issue within the engine management system or emission control. As with other check engine light scenarios, you need to schedule diagnostic service and repair. However, you should not keep driving your car until it is fixed.

Blinking Check Engine Light

The most dangerous situation involving a service engine light is when the light steadily blinks. Steady blinking indicates a very serious issue. You need to pull your vehicle off the road or into a safe area immediately and stop driving it. Otherwise, you risk serious engine failure, particularly in regard to the emission control system. You can damage the catalytic converter or even start an engine fire. Have your vehicle towed for immediate attention at Carolina Auto Service.
