Vehicle Diagnostic - E.M.A Tire & Auto

Q: What does it mean when my check engine light comes on?

A check engine light can indicate various issues, from a loose gas cap to serious engine or emission problems. A diagnostic scan retrieves trouble codes so technicians can identify the exact cause.

Q: How much does a diagnostic service cost?

Our basic diagnostic scan starts at $89.95, covering code retrieval and interpretation. Additional testing or inspection may involve extra costs, and we always provide an estimate before proceeding.

Q: How long does a diagnostic service take?

A standard diagnostic scan takes roughly 30-60 minutes. Complex issues may require extended testing; we share an estimated timeline when you schedule your visit.

Q: Can I drive with my check engine light on?

A steady check engine light usually means you can drive briefly, but schedule a diagnostic soon. A flashing light signals a severe issue—safely pull over and arrange towing to prevent damage.

Q: Will the check engine light reset itself after a repair?

After repairs, we reset the light with diagnostic equipment. Occasionally it clears after several drive cycles if the issue is resolved, but this approach is unreliable.

Frequently Asked Questions

What does it mean when my check engine light comes on?

A check engine light can indicate various issues, from something as simple as a loose gas cap to more serious engine or emission system problems. The only way to know for certain is to have the vehicle's computer system scanned for diagnostic trouble codes.

How much does a diagnostic service cost?

Our basic diagnostic scan starts at $89.95. This includes retrieving and interpreting error codes from your vehicle's computer system. More comprehensive diagnostics that require additional testing or component inspection may have additional costs. We always provide a detailed estimate before performing any work.

How long does a diagnostic service take?

A basic diagnostic scan typically takes about 30-60 minutes. More complex issues may require additional time for thorough testing and inspection. We'll provide you with a time estimate when you schedule your service.

Can I drive with my check engine light on?

It depends on the cause. A steady check engine light usually means you can drive the vehicle for a short time, but you should have it checked as soon as possible. A flashing check engine light indicates a serious problem that could damage your vehicle if you continue driving. In this case, you should pull over safely and have your vehicle towed to our service center.

Will the check engine light reset itself after a repair?

In most cases, we need to reset the check engine light using our diagnostic equipment after completing repairs. Sometimes the light will turn off on its own after several drive cycles if the problem has been resolved, but this isn't always reliable.
