The Check Engine light is an important dashboard warning that indicates a potential issue within your vehicle’s engine or related systems. It can be triggered by a wide range of problems, from minor issues like a loose gas cap to more serious concerns such as engine misfires or emissions system faults.

This warning light is part of your vehicle’s Onboard Diagnostics (OBD) system, which continuously monitors engine components and sensors to ensure proper operation. When a problem is detected, the system stores a diagnostic trouble code (DTC) and illuminates the Check Engine light. Technicians can read this code using an OBD scanner to accurately identify the source of the issue.

Although the Check Engine light does not always indicate how severe the problem is, it should never be ignored. Driving with the light on can lead to further damage and more costly repairs. A steady light means your vehicle should be inspected as soon as possible, while a flashing light signals a more serious issue and requires immediate attention
