The check engine light could be illuminated in a 2016 Buick Enclave due to various factors like a loose gas cap, faulty ignition coil, malfunctioning MAF sensor, or worn spark plugs. You might be curious about the importance of ignition coils in your car's engine and how they operate. Essentially, ignition coils act as compact electrical transformers. Their role is to convert the low 12-volt current typically present in car batteries into a higher voltage necessary to ignite the fuel and initiate the engine. Each spark plug in a vehicle has its individual ignition coil. If you ever need to replace the coils, the average cost for fixing an ignition coil ranges from $260 to $380, covering both labor expenses and the parts' cost.
