Automotive diagnostics at Fort Gibson Tire & Auto

Answers first, repairs second

Automotive Diagnostics

A warning light is a starting point, not a diagnosis. We pull the codes, test the systems behind them, and tell you what's actually failing — so repairs start with facts.

When We Recommend Diagnostics

If your vehicle is telling you something's off, a diagnostic is how we find out what.

Dashboard Warning Lights

  • Check engine
  • ABS / traction control
  • SRS / airbag
  • TPMS / tire pressure
  • Battery / charging system
  • Emissions / catalytic converter

Drivability Issues

  • Rough idle or stalling
  • Misfires or hesitation under load
  • Hard starting, no-start
  • Poor fuel economy
  • Shifting issues and transmission codes
  • Noises, vibrations, or pulls you can't trace

How a Diagnostic Works

Code reading is step one, not the whole job. A real diagnosis tests the circuits and components behind the code.

Our Diagnostic Process

  • Scan every available module, not just the engine
  • Review freeze-frame data and live sensor values
  • Test the components and wiring behind the code
  • Confirm the actual failure before quoting
  • Explain findings in plain language

Starting At

$76.99

Diagnostic fee covers scan and system testing. If you approve the repair, your final estimate is clear up front.

Common Questions

Quick answers before you bring the vehicle in.

Can't I just get the code read for free?

A parts store can pull a stored code, but a code only points at a system — not the failed part. Replacing parts based on the code alone is how people spend money twice.

Will you clear the code after you diagnose it?

Yes. Once we confirm the issue, we clear codes as part of the repair and verify the fix with a road test.

The light came on and went off on its own — should I still bring it in?

Most modern vehicles store a pending code even when the light clears. A scan shows what the vehicle saw. It's worth checking before a harder failure happens.

Can you diagnose electrical issues?

Yes. We trace wiring, grounds, and circuit faults using proper test equipment — not guesswork.
