What Does the Check Engine Light Mean?

Your Check Engine Light is part of your vehicle’s onboard diagnostics system (OBD-II). It constantly monitors your engine, emissions, and major components for any irregularities. When something’s not working the way it should, the system triggers a warning light on your dashboard—usually in the shape of an engine or labeled “Check Engine.”

Common reasons your Check Engine Light might come on:

Loose or faulty gas cap
Oxygen sensor failure
Catalytic converter problems
Mass airflow (MAF) sensor issues
Spark plug or ignition coil failure
Emissions control system faults
Vacuum leaks
Faulty fuel injectors
Transmission-related problems

Some issues are minor and easy to fix. Others can cause serious damage if ignored. That’s why it’s important to get professional diagnostics as soon as the light comes on.

Flashing vs. Solid Check Engine Light: What’s the Difference?

When your Check Engine Light comes on, the way it behaves can give you a clue about the severity of the issue.

Solid (steady) light: This usually indicates a non-emergency issue that still needs attention. It could be a loose gas cap or a sensor issue, but it won’t necessarily cause immediate damage. Still, don’t ignore it—bring your car in for a quick Check Engine Light Service.
Flashing light: This means there’s a serious problem, often related to misfires or major component failure. A flashing light usually means stop driving immediately and have your vehicle inspected to prevent major engine or emissions system damage.

If you’re ever unsure, give us a call or stop by. At D&E Auto Repair, we’ll help you figure out what’s going on and what to do next.

Our Check Engine Light Diagnostic Process

At D&E Auto Repair, we don’t just read the code and send you on your way—we get to the root of the problem. When you bring in your vehicle for Check Engine Light Service, our technicians take the time to dig deeper, using advanced diagnostic equipment and their hands-on expertise.

Here’s what our process looks like:

Code Scan: We hook up to your vehicle’s OBD-II system to retrieve trouble codes.
System Testing: We perform additional testing based on the code (fuel system, ignition, sensors, etc.).
Visual Inspection: We check key components for wear, leaks, or damage.
Repair Recommendations: We explain what we found, what needs fixing, and what your options are.
Post-Repair Scan: After the repair, we clear the code and confirm the issue is resolved.

We won’t just tell you the code and leave you guessing—we’ll show you what’s going on and help you make an informed decision, without pressure or confusion.

Why You Shouldn’t Ignore a Warning Light

It’s tempting to brush off that warning light, especially if your car seems to be driving fine. But many issues that trigger the Check Engine Light can silently damage your engine, catalytic converter, or transmission over time. Ignoring it can lead to more expensive repairs later—and even safety risks.

Risks of ignoring a Check Engine Light:

Reduced fuel economy
Increased emissions
Potential engine overheating or failure
Failed smog or emissions testing
Damage to catalytic converter or oxygen sensors
Worsening of minor issues into major repairs

If your Check Engine Light is on, your car is trying to protect itself—and you. Let us help you catch the problem early and fix it before it leads to bigger trouble.
