What is the significance of the check engine light?

The check engine light (CEL) is a crucial warning signal on your car’s dashboard that notifies you of possible problems with your engine, emissions, or another system. It’s a key component of your vehicle’s onboard diagnostics (OBD-II) system and is also known as the malfunction indicator lamp. The OBD-II system constantly monitors various sensors and components in your car. When the light comes on, it indicates that the OBD-II system has detected an issue, such as a faulty sensor, an emissions problem, or an engine component malfunction. Although the light doesn’t specify the exact problem, it acts as an early warning system, reminding you to consult professional check engine light diagnostics and repairs to prevent potential damage and ensure your car’s ongoing performance and dependability.
