Reviewing the Check Engine Light

The check engine light (CEL) is a warning light that appears on the dashboard of your vehicle when there is a problem with your engine, emissions, transmission, or other systems. This light is connected to the onboard diagnostics system (OBD-II), which is a computer system that monitors the various components of your vehicle. When an issue is detected, the OBD-II system generates a diagnostic trouble code (DTC), also called a fault code, and sends it to your vehicle’s internal computer. It also triggers the check engine light to turn on. The DTC can only be read via a code-scanning tool to identify the problem and determine the necessary repair. The check engine light is an important function that alerts you to potential issues and helps prevent further damage by encouraging prompt attention.
