How long do you need to drive reset check engine light?

Driving will typically not reset a Check Engine Light (CEL). The CEL is generally triggered when the vehicle's on-board diagnostic (OBD) system detects a fault or issue with the vehicle's emission control system or engine. To reset the CEL, the underlying issue that caused the light to come on needs to be addressed. This may involve inspecting the vehicle, diagnosing the issue, and making necessary repairs or clearing any stored error codes. Simply driving the vehicle, without addressing the root cause of the CEL, is unlikely to reset the light.
