Engine Diagnostics & Check Engine Light in Seminole, FL

📍 9660 Seminole Blvd, Suite B, Seminole, FL 33772☎ (727) 851-9838

A trouble code tells you which circuit reported a problem — not what is wrong. Anyone can read a code. Diagnosing it properly takes time and testing, which is what we do rather than replacing parts and hoping. Diagnostic inspections start at $155.00 + tax.

Common questions

Is a free code read the same as a diagnosis?

No, and this is where a lot of money gets wasted. A free code read gives you a number. That number points at a system, not a failed part — a single code can have half a dozen possible causes, from a cheap sensor to a wiring fault to a mechanical problem elsewhere. Proper diagnosis means testing to find which one it actually is, so you replace the right part once instead of the wrong parts repeatedly.

My check engine light is flashing. Can I keep driving?

A flashing light is different from a steady one and should be treated as urgent. It usually indicates a misfire severe enough to damage the catalytic converter, which is an expensive part. Reduce speed, avoid heavy acceleration, and get it looked at promptly rather than finishing the week on it.

Every vehicle gets a digital inspection

Our technicians use iPads to photograph what they find, so you can see the actual condition of your vehicle and decide what is urgent and what can wait. Vehicle inspections start at $89.99 + tax.
