What Does the Check Engine Light Mean?
Your car’s check engine light is part of the onboard diagnostic system (OBD-II). When it comes on, your car’s computer is letting you know something isn’t working the way it should. That could mean anything from a loose gas cap to a serious engine issue.
While some problems are minor, others could result in:
- Reduced fuel economy
- Poor engine performance
- Emissions failures
- Internal engine damage
Ignoring the light—especially if it’s flashing—can lead to more costly repairs and even breakdowns.
Steady vs. Flashing: What’s the Difference?
There’s a big difference between a solid check engine light and a blinking one.
- Solid Light: This usually signals a non-urgent problem like a faulty sensor, emissions issue, or minor misfire. It’s safe to drive for a short time, but you should get it checked soon.
- Flashing Light: This means a serious issue—often a major engine misfire that can damage your catalytic converter or engine. Pull over safely and call us right away.
If your light is flashing, don’t wait. We’ll prioritize your vehicle and get it diagnosed as soon as possible.
What Triggers a Check Engine Light?
Here are just a few common causes behind that frustrating little light:
- Faulty oxygen sensor
- Loose or damaged gas cap
- Catalytic converter failure
- Mass airflow sensor issues
- Spark plug or ignition coil failure
- Evaporative emissions system leaks
- Transmission problems
- Vacuum system leaks
- Fuel injector malfunction
At Signal Garage, we use professional-grade scan tools and extensive diagnostic testing—not just a code reader—to accurately identify the source of the problem.
How Our Diagnostics Process Works
Getting your check engine light diagnosed shouldn’t feel like a mystery. At Signal Garage, we walk you through the process with full transparency and no pressure.
Our process includes:
- Initial scan using professional OBD-II tools to read trouble codes
- Pinpoint testing to determine the root cause—not just the symptom
- Digital inspection with photos and detailed notes
- Straightforward explanations so you know what’s urgent, what can wait, and what your options are
- Approved repairs using high-quality parts and expert techniques
- Final verification to ensure your vehicle is performing as it should
We don’t clear the code and send you on your way. We fix the problem—and we explain everything clearly along the way.

Common Myths About Check Engine Lights
There’s a lot of misinformation out there. Let’s clear a few things up:
“It’s probably just the gas cap.”
It might be—but even then, your system still needs to be reset. And if tightening the cap doesn’t work, it could be a leak or sensor issue.
“I can just clear the code myself.”
Sure, but the issue will come back if it’s not fixed—and you might erase important diagnostic data. Always let a professional assess it first.
“My car runs fine, so it can’t be serious.”
Modern engines compensate for issues to keep you moving. But performance problems can still cause long-term damage without obvious symptoms.
