Code P2314 Mercury Description

The P2314 diagnostic trouble code (DTC) for Mercury vehicles specifically refers to the Ignition Coil 'E' Secondary Circuit. This code indicates that there is an issue with the secondary circuit of the ignition coil designated as 'E'. The ignition coil is a crucial component in the ignition system of a vehicle, responsible for converting the low voltage from the battery into the high voltage needed to ignite the fuel mixture in the engine cylinders. The secondary circuit of the ignition coil is responsible for delivering this high voltage spark to the spark plugs.
