Your 2015 Ford Explorer's Check Engine Light serves as a notification when there's an issue with your emissions system. This could range from a minor thing like not tightening the gas cap to something more severe like a blown head gasket. Start by inspecting the gas cap, as the vehicle's computer monitors tank pressure to prevent fuel vapors from escaping, affecting fuel efficiency and the environment. If the gas cap isn't the problem, a faulty oxygen sensor is the likely culprit, testable with an OBD2 scanner.
