What the Check Engine Light Really Means
The check engine light is one of your vehicle’s On-Board Diagnostics (OBD-II) systems. When the computer detects a question affecting depiction, emissions, or security, it triggers the light. In many cases, the issue is narrow but can worsen if neglected. In others, the warning displays that immediate consideration is needed.

Either way, the light should never be removed.
