The check engine light monitors your car's major components, including the engine, transmission, and emissions system. When something goes wrong, the dreaded orange or yellow light alerts you.

There are two main types of check engine light warnings:

  • Steady Light

A non-blinking check engine light means a problem needs attention but is not necessarily urgent. You should schedule an appointment for diagnostics as soon as possible.

  • Flashing Light

A flashing check engine light indicates a more serious issue, such as an engine misfire, which can cause damage to your catalytic converter if not addressed immediately. In this case, you should pull over and stop driving right away.

“Why Did My Check Engine Light Come On”

The check engine light can come on for various reasons, from minor issues to serious mechanical problems. To get the answer to this frequently asked question, you must start with a scan for error codes along with diagnostics and inspections. Below are a few of the most common explanations for an illuminated check engine light:

  • Loose Gas Cap
  • Oxygen Sensor Failure
  • Faulty Catalytic Converter
  • MAF Sensor Issues
  • Ignition Coil
  • Spark Plugs
