Understanding Your Check Engine Light
Your check engine light is part of your vehicle’s onboard diagnostics system (OBD-II), which monitors engine performance and critical systems. When it illuminates, your vehicle’s computer has detected a problem that could affect performance, fuel efficiency, or other important vehicle functions.

Signals a severe problem, often engine misfires that can damage your catalytic converter. Reduce speed immediately and contact Atlanta Speedwerks to avoid costly repairs.
Common Reasons Your Check Engine Light Activates
Here are the most common culprits we diagnose at our Gainesville shop:
- Oxygen Sensor Failure: Leads to decreased fuel efficiency and reduced engine performance.
