What does MIL stand for in a car?

MIL stands for "Malfunction Indicator Lamp." It is a warning light on a vehicle's dashboard that indicates a problem with the engine or emissions control system. When the MIL is illuminated, it typically means that the vehicle's onboard diagnostics system has detected an issue that may require attention. Drivers should consult their vehicle's manual and consider having the car checked by a professional to diagnose the problem.
