The Ignition Coil in Ford Expedition vehicles work with the important duty of stepping up the electricity flow in the car from 12 volts to 15,000 - 40,000 volts required to ignite the air/fuel mixture in the engine's cylinders. By using a primary circuit which comprises the battery and the switch, the current flows and in the secondary circuit, the current flows to the spark plugs. An ignition coil can be made up of two insulated copper wire coils that are wound round an iron core, where the primary winding turns usually have fewer layers of thicker wire than the secondary winding turned with several layers of thinner wire. As the model year has progressed, the Ford Expeditions have incorporated the choice ignition coil style, including the coil pack, coil on plug, and wasted ignition arrangements. Older models generally used a single coil pack arrangement but newer models use the COP systems where individual coils are associated with each spark plug. The main one is concerned with the efficiency and the performance, COP systems delivering a more direct and a far more reliable ignition. DTC and OTC signs of ignition coil failure include rough running, poor fuel economy, hard starting, and should therefore be replaced on time to enhance vehicle performance.
