What Your Check Engine Light Means

The check engine light is part of your car's onboard diagnostics system. When this light appears, your vehicle’s computer detects a potential issue within its systems. Common causes include:

  • Loose or damaged gas cap affecting fuel pressure.
  • Malfunctioning oxygen sensor or other emissions components.
  • Engine misfires caused by faulty spark plugs or ignition coils.
  • Catalytic converter issues that can reduce efficiency.
