Engine Diagnostics in Troy and Roseville: Identifying Problems Before They Grow
When your car’s “Check Engine” light comes on, it’s easy to ignore—especially if the vehicle still runs fine. For drivers in Troy and Roseville, delaying a diagnostic can turn a minor issue into a costly repair.
Why Engine Diagnostics Are Important
Modern vehicles use a network of sensors and an ECU to monitor performance. When something isn’t right, the car stores a trouble code and illuminates the light. Diagnostics retrieve those codes and pinpoint the issue before serious damage occurs.
Common Reasons for a Check‑Engine Light
- Loose or damaged gas cap
- Faulty oxygen sensor
- Worn spark plugs or ignition coils
- Catalytic converter issues
- Mass‑airflow sensor problems
