When your check engine light turns on, start with testing—not guessing.
Kelly’s Automotive has served Rogue Valley drivers since 2004. We’re an award-winning, AAA-approved shop focused on modern diagnostics, electrical repair, and reliable maintenance. Our Medford team treats you like a neighbor and your vehicle like family.
A flashing or steady check engine light can signal anything from a loose gas cap to engine misfires or catalytic converter issues. Early testing helps prevent costly damage and keeps your vehicle road-ready.
We retrieve diagnostic trouble codes (DTCs) and then confirm the root cause with hands-on testing. You’ll know what we found, why it matters, and what it will take to fix it.
Many engine faults reduce power and fuel efficiency. Accurate diagnostics restore drivability and help you avoid wasting money at the pump.
Every vehicle system talks to your onboard computer. When something falls outside normal range, it stores a code and triggers the warning light. Here’s what our Medford diagnostic service includes:
We connect professional-grade scan tools to read stored and pending DTCs. This gives us a starting point—but it’s only step one.
Codes don’t always tell the full story. We test sensors, wiring, fuel delivery, ignition components, and emissions systems to confirm the failure before recommending repairs.
Modern vehicles rely on complex electrical networks. Our team specializes in tracking down shorts, voltage drops, and communication faults.
If your vehicle failed DEQ testing in Medford or won’t set readiness monitors, we diagnose the underlying issue and guide you through the repair process.
After testing, we explain your options in plain language. You’ll receive a written estimate and timeline before any work begins.

Diagnostic costs depend on the time and testing required. We provide clear pricing before we begin so you know what to expect.
Not always. A stored code points to a system, not necessarily a failed part. That’s why we perform follow-up testing to confirm the root cause before recommending repairs.
