Engine Diagnostics — Frequently Asked Questions

How much does an engine diagnostic cost in Atlantic Beach, FL?

Engine diagnostic fees typically range from $75–$150 for a professional scan and code reading. We provide a clear, upfront estimate based on what we find — and if you proceed with repairs, the diagnostic fee may be applied toward the repair cost.

How long does a car diagnostic take?

A basic OBD-II scan takes 30–60 minutes. A more thorough diagnostic — including road testing and inspecting related components — typically takes 1–2 hours. We'll let you know what to expect based on your vehicle's symptoms when you drop it off.

What does it mean if my check engine light is flashing?

A flashing check engine light indicates an active engine misfire that could damage your catalytic converter. This is more urgent than a steady check engine light — avoid hard acceleration and get to a shop as soon as possible. Call us at (904) 337-0738 and we'll get you in quickly.

Will a diagnostic scan tell me everything that's wrong with my car?

A diagnostic scan reads fault codes stored in your vehicle's computer, which points us to systems with issues. It doesn't automatically identify every mechanical problem, but it gives us a precise starting point. Our technicians combine the scan results with a visual inspection to give you a complete, honest picture.
