You can determine the severity of the issue based on how the check engine light appears on your dashboard:

Solid Red: The issue is more severe, so pay attention to how your vehicle performs. If you detect no change in vehicle performance, it may be safe to continue driving to an engine service repair center.

Blinking: If your check engine light is blinking, pull over immediately, turn off your engine, and call your roadside assistance provider. This can indicate a misfiring engine and unburned fuel may get into the exhaust system, causing catastrophic damage.
