Code P2304 Lincoln Description
When a Lincoln vehicle displays the diagnostic trouble code (DTC) P2304, it indicates a problem with the ignition coil 'B' primary control circuit being too high. This code specifically pertains to the primary control circuit of the ignition coil associated with cylinder 'B' in the engine. 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 create a spark in the spark plugs. The primary control circuit controls the timing and duration of the spark, ensuring proper combustion within the engine.
