Check Engine Light Diagnostics in West Nashville

A check engine light means your car's computer has found a problem and stored a code. Diagnostics read that code and test the car to find the real cause before any repair.

When to call a shop

If the light is steady, have it checked soon. If it is flashing, pull over safely and have the vehicle towed, since flashing can mean serious engine damage.

Frequently asked questions

Can I keep driving with the check engine light on?

If the light is steady and the car drives normally, you can usually drive a short while but should get it checked soon. A flashing light is more serious, so pull over safely and arrange a tow.

Why not just use a free code reader?

A code reader tells you the stored code, but not always the true cause. The same code can come from several different problems, so a shop tests further to avoid replacing the wrong part.

Is a flashing check engine light an emergency?

A flashing light often means a serious misfire that can damage the catalytic converter. It is best to stop driving when safe and have the vehicle towed to a shop rather than risk further damage.

Will the light reset on its own?

Sometimes a light clears after the problem stops, such as a loose gas cap that gets tightened. If it keeps coming back, the underlying issue still needs to be diagnosed and fixed.
