What the Check Engine Light Means

When your check engine light comes on, it means your vehicle’s on-board diagnostics have identified a problem with one or more important systems. While it could be something as simple as a gas cap that isn't secured, it could also be something as critical as a failed oxygen sensor or a clogged catalytic converter. If it’s something serious, continuing to drive your vehicle could cause serious damage to your engine or exhaust system.

Here are the major systems that could cause the check engine light to come on:

  • Vacuum System: Loss of pressure in your vacuum system will trigger the check engine light. Pressure loss can come from a variety of sources, including a loose gas cap, bad vacuum hoses, or a faulty exhaust gas recirculation valve.
  • Oxygen Sensor: In addition to extreme loss of fuel economy, a bad O2 sensor can also cause major damage to your spark plugs and catalytic converter.
  • Ignition System: Your vehicle’s ECU monitors the spark plugs, spark plug wires, and ignition coil. A problem with these systems will cause fuel economy and performance issues, as well as trigger the check engine light.
  • Catalytic Converter: One of the worst problems to continue to operate your vehicle with is a bad catalytic converter. Doing so can cause your engine to run hot, which can lead to internal engine damage. Your vehicle can also lose power, as well as fuel economy. A bad catalytic converter can also cause a failure at your next emissions test
  • Mass Airflow Sensor: Like the oxygen sensor, the mass airflow sensor must function properly to get optimal performance and fuel economy. Also a bad MAF sensor can damage spark plugs, the catalytic converter, and even the O2 sensor.
