Frequently Asked Questions (FAQ)

Why is my check engine light on?

Your check engine light can come on for many reasons, including sensor issues, ignition problems, emissions faults, fuel system concerns, or engine performance problems. A professional diagnostic scan is the best way to identify the exact cause.

Is it safe to drive with the check engine light on?

If the light is steady, the issue may not be urgent, but it should still be inspected soon. If the light is flashing, it could indicate a serious problem that may damage your engine and should be addressed immediately.

What does a flashing check engine light mean?

A flashing check engine light often signals a severe engine misfire or another major issue that could damage your catalytic converter or engine if ignored.

What happens during a check engine light diagnostic?

A diagnostic service may include:

Computer scanning for trouble codes
Inspecting sensors and engine systems
Testing electrical components
Road testing if needed
Identifying repair recommendations

Can a loose gas cap cause the check engine light to come on?

Yes. A loose, damaged, or missing gas cap can trigger the check engine light because it affects your vehicle’s emissions system.

Will the check engine light turn off by itself?

Sometimes the light may turn off if the issue resolves itself, but the underlying problem should still be checked to prevent future issues.

What are common reasons for a check engine light?

Common causes include:

Faulty oxygen sensors
Bad spark plugs or ignition coils
Catalytic converter problems
Loose gas caps
Vacuum leaks
Fuel injector issues
Mass airflow sensor failures

What’s the difference between the check engine light and maintenance light?

The maintenance light typically reminds you about scheduled service, while the check engine light indicates a problem detected by your vehicle’s onboard computer.

Do you diagnose check engine lights on all vehicle makes and models?

Yes. Bolt Auto Care services many domestic and import vehicles, including cars, trucks, and SUVs.

How long does a check engine light diagnostic take?

Most diagnostics can be completed within an hour, though more complex issues may require additional testing.
