Vehicle Diagnostics in Stratford, ON

Is your check engine light on? Is something just not feeling right? Perth Tire & Auto uses professional-grade diagnostic equipment and experienced technicians to identify exactly what's wrong — the first time. We serve drivers in Stratford, Mitchell, St. Marys, and across Perth County.
 

Check Engine Light Diagnostics

A check engine light can mean anything from a loose gas cap to a serious engine concern. We don't just read codes and guess — we verify the root cause before recommending any repair. Our process includes:
  • OBD-II fault code retrieval and analysis
  • Live data monitoring
  • Visual and functional component testing
     

Full Vehicle System Diagnostics

Modern vehicles have multiple control modules that communicate with each other. A problem in one area can affect others. We diagnose issues across:
  • Engine management and fuel systems
  • Transmission and drivetrain controls
  • ABS, traction control, and stability systems
  • Airbag and safety systems
  • Charging and starting systems
  • HVAC and climate control electronics
     

Driveability & Performance Issues

Not all problems trigger a warning light. We also diagnose rough running, misfires, poor acceleration, hard starting, stalling, and reduced fuel efficiency — even intermittent issues that are hard to reproduce.
