Common Reasons for a Check Engine Warning Light
Your vehicle’s onboard computer tracks dozens of systems. When something’s off, it triggers the Check Engine Light. Some of the most common causes include:
- Loose or damaged gas cap
- Faulty oxygen sensor
- Catalytic converter issues
- Mass airflow sensor malfunction
- Misfiring spark plugs or ignition coils
- Transmission system alerts
- Exhaust or emission system problems
Even a small issue, if ignored, can snowball into a costly repair. Getting timely Check Engine Light Service is the best way to prevent bigger problems.
Our Comprehensive Check Engine Light Diagnostics
At DMA Automotive, we go beyond simple code reading. Our process ensures we find the root cause, not just the symptom.
Step 1: Code Reading
We use advanced scanners to retrieve fault codes from your vehicle’s onboard computer.
Step 2: System Testing
Once we know where the problem lies, we test the specific system (fuel, ignition, emissions, etc.) to confirm.
Step 3: Component Inspection
We physically inspect components like spark plugs, wiring, and sensors for wear or failure.
Step 4: Repair Plan
Our technicians provide a clear explanation of what needs repair or replacement, with cost and time estimates.
Step 5: Post-Repair Testing
We recheck your vehicle to make sure the warning light stays off and your car is running smoothly.
Signs You Shouldn’t Ignore a Check Engine Light
Not all warning lights mean the same level of urgency. Pay attention to how your car behaves:
- Steady light – Indicates a non-urgent issue that still needs prompt attention.
- Flashing light – Signals a severe problem, like engine misfiring, that could damage the catalytic converter.
- Performance changes – Loss of power, rough idling, or poor fuel economy often accompany a check engine alert.
- Strange sounds or smells – Knocking, backfiring, or unusual exhaust odors may point to serious problems.
If your light is flashing, it’s best to stop driving and call for assistance immediately.

Benefits of professional diagnostics at DMA Automotive include:
- Preventing misdiagnosis and unnecessary repairs.
- Detecting related issues before they cause breakdowns.
- Ensuring your car passes emissions inspections.
