Check Engine Light Diagnostics in Norfolk, VA
Has your Check Engine Light come on? Don't ignore it. While some warning lights may indicate a minor issue, others can signal problems that affect vehicle performance, fuel economy, emissions, or even engine safety.
At CompuTune Car Care, our ASE-certified technicians use advanced diagnostic equipment and testing procedures to accurately identify the cause of your Check Engine Light and recommend the appropriate repairs.
What Does the Check Engine Light Mean?
The Check Engine Light is part of your vehicle's onboard computer system. When the vehicle detects a problem within the engine, emissions, fuel, ignition, transmission, or related systems, it stores a diagnostic trouble code and illuminates the warning light.
The Check Engine Light is your vehicle's way of telling you something isn't operating as intended. Ignoring it can sometimes allow a minor problem to grow into a much more expensive repair.
The Light May Appear As:
Solid vs Flashing Check Engine Light
Understanding the Difference
Solid Check Engine Light
A steady Check Engine Light often indicates a fault that should be diagnosed soon but may not require immediate shutdown of the vehicle.
Flashing Check Engine Light
A flashing Check Engine Light typically indicates an active engine misfire that may cause catalytic converter damage or severe engine performance issues.
If your Check Engine Light is flashing:
Prompt diagnosis can help prevent additional damage and costly repairs.

Frequently Asked Questions
Can I drive with my Check Engine Light on?
A steady Check Engine Light may allow limited driving depending on vehicle symptoms. However, the issue should be diagnosed promptly to avoid further damage.
Why is my Check Engine Light on if my vehicle seems fine?
Many faults begin before noticeable symptoms occur. The vehicle's onboard computer may detect issues before they become obvious to the driver.
Will clearing the code fix the problem?
No. Clearing a code typically removes the warning light temporarily but does not correct the underlying fault.
How long does diagnostic testing take?
Diagnostic time varies depending on the nature of the concern and the testing required to accurately identify the failure.
Can a loose gas cap cause a Check Engine Light?
Yes. On many vehicles, a loose or faulty gas cap can trigger certain emissions-related fault codes.
