Quizplus · Accepted Answer

Not all codes will cause the Malfunction Indicator Lamp (MIL), commonly known as the check engine light, to illuminate. Some diagnostic trouble codes (DTCs) are stored in the vehicle's computer system without triggering the MIL, especially if they are for pending or minor issues that do not immediately affect the vehicle's operation or emissions system.
