Why Your Check Engine Light Comes On

The check engine light is part of your vehicle’s onboard diagnostics system. When it detects something unusual, it triggers the light to alert you. Common reasons include:

  • Loose or faulty gas cap
  • Oxygen sensor failure
  • Worn spark plugs or ignition coils
  • Mass airflow sensor issues
  • Catalytic converter problems
  • Transmission-related errors


What To Do If Your Check Engine Light Turns On

  1. Don’t Ignore It – Some issues can cause serious damage if left alone.
  2. Check for Simple Fixes – Tighten your gas cap and see if the light turns off after driving.
  3. Schedule a Diagnostic – If the light stays on, bring your car in for a scan.
