Code P1365 Mercury Description
When the diagnostic trouble code P1365 appears on a Mercury vehicle, it indicates a failure within the ignition coil secondary circuit. The ignition coil is responsible for converting the low voltage from the battery into the high voltage needed to ignite the fuel-air mixture in the engine cylinders. In this case, the secondary circuit failure means that there is a problem with the coil's ability to produce the necessary spark, which can lead to misfires, rough idle, and overall poor engine performance. If left unaddressed, this issue can cause further damage to the engine and result in decreased fuel efficiency and increased emissions.
