Common Car Warning Lights and What They Mean

Check engine light

Like most people, you’ve probably seen a warning light come on in your car, and wonder “What does this mean?” — today we’re going to help answer that for three common warning lights.

“Check engine” light

The check engine light is connected to your car’s computer, and is one of the most common warning lights seen. It can be caused by a variety of issues, from simple to potentially dangerous.

  • A loose gas cap. A common reason for the check engine light is certainly a simple one. Try tightening it and see if the light goes away.
  • Sensors
  • Spark plugs
  • Other engine issues

“Dirty Air Filter” light

This light means that your engine air filter may be obstructed or dirty. A common fix is resetting the button as well as getting the filter replaced. To learn more about the air filters in your car, check out our articles on them here: The filters in your vehicle, and How to replace your air filter and cabin air filter.

“Break wear” light

A break wear light, more common in newer cars, means that the sensor has indicated your brake pads are thin. If you are unsure if this light is correct, try resetting the indicator. We recommend booking a mechanic when you see this light, as it’s important to have the break pads replaced.
