As a family-owned auto repair shop near the Willow Glen neighborhood, we’ve built our reputation on straightforward, honest service for both foreign and domestic vehicles.

Common Reasons Your Check Engine Light Turns On
A check engine light can signal problems with multiple systems in your vehicle, which is why proper diagnostics matter so much. Common reasons your check engine light may illuminate include:
- A loose or damaged gas cap
- Worn spark plugs affecting engine performance
- Sensor failures, including oxygen or mass airflow sensors
- Issues within the exhaust system
- Engine misfires
- General wear and tear on engine components
A steady check engine light usually means it’s worth scheduling a diagnostic soon, while a flashing light often points to a more serious issue. If your check engine light is flashing, it’s best not to wait, since continuing to drive could lead to further damage.
Our Check Engine Light Diagnostic Process
When you bring your vehicle to GIC Car Clinic for a check engine light, our technicians perform a comprehensive diagnostic scan using professional equipment to pull specific information about what’s triggering the warning. From there, we walk you through exactly what we found and what it means for your vehicle.
Our diagnostic process typically includes:
- A full scan to identify the specific trouble code or codes
- A physical inspection of related systems and components
- A clear explanation of the root cause, not just the code itself
- A straightforward recommendation for the repair needed, with an upfront estimate before any work begins
We believe in transparent pricing, so you’ll know what to expect before we move forward with any repair.
Why Ignoring a Check Engine Light Can Cost You More
It’s easy to assume a check engine light isn’t urgent, especially if your car still seems to be running fine. But ignoring it can let a smaller issue turn into a major repair.

Our ASE-certified technicians have decades of collective experience diagnosing these issues correctly the first time, so you’re not paying for guesswork or unnecessary parts.

Frequently Asked Questions
What are the most common reasons a check engine light comes on?
Common causes include a loose gas cap, worn spark plugs, sensor failures, exhaust system issues, and engine misfires. A proper diagnostic scan is the best way to determine which of these, or something else entirely, is causing your specific warning light.
Is it safe to keep driving with my check engine light on?
It depends on whether the light is steady or flashing. A steady check engine light usually means it’s worth scheduling a diagnostic soon, but it’s generally not an immediate emergency. A flashing check engine light is a more urgent signal of a severe issue, and it’s best to have your vehicle looked at as soon as possible to avoid further damage.
What happens during a check engine light diagnostic?
We perform a comprehensive scan to pull the specific trouble codes your vehicle is generating, then follow up with a physical inspection of the related systems. This combination helps us pinpoint the actual root cause rather than just reacting to a single code, so you get an accurate diagnosis and a clear recommendation.
Can a loose gas cap really trigger my check engine light?
Yes. A loose or damaged gas cap is one of the simpler, more common reasons a check engine light comes on, since it can affect your vehicle’s fuel system pressure. It’s an easy thing to check before assuming the issue is something more serious.
How much does it cost to find out why my check engine light is on?
The cost of a check engine light diagnostic depends on what’s needed to identify the issue. We provide upfront estimates before any work begins, so you’ll know what to expect before committing to a diagnostic or repair.
