Why Is the Check Engine Light On? 

Picture this: you’re cruising along, enjoying the sunshine, and then—bam—your dashboard lights up like it’s Christmas. That check engine light could be pointing to anything from a loose gas cap to something more serious under the hood. 

Here are a few common culprits: 

  • Loose or Damaged Gas Cap: It seems small, but a loose cap can mess with your fuel system. 
  • Faulty Spark Plugs: These little parts ignite your engine’s fuel. If they’re misfiring, your light might pop on. 
  • Oxygen Sensor Issues: Your car relies on this sensor to measure emissions. When it’s out of order, efficiency goes down. 
  • Catalytic Converter Trouble: This component reduces harmful emissions. Ignoring it? Not a good idea. 

The light is your car’s way of saying, “Help me out here!” But don’t panic just yet.
