Mercury P1364 Code Description
The diagnostic trouble code P1364 (DTC) for Mercury vehicles indicates a problem with the ignition coil primary circuit. The ignition coil plays a crucial role in the engine’s ignition system by converting the battery’s low voltage into the high voltage needed to ignite the spark plugs. The ignition coil’s primary circuit controls the switching of current flow to generate the spark. When this circuit malfunctions, it can lead to various performance issues in the vehicle.
