Code P2307 Mercury Description
The diagnostic trouble code P2307 for Mercury vehicles indicates a problem with the ignition coil 'C' primary control circuit being too high. The ignition coil is responsible for converting the low voltage from the battery into the high voltage needed to create a spark for the spark plugs. In this case, the primary control circuit refers to the part of the ignition system that controls the timing and duration of the spark.
Common Causes of P2307 Mercury
- Faulty ignition coil 'C'
- Damaged wiring or connectors in the ignition system
- Malfunctioning powertrain control module (PCM)
- Worn out spark plugs or spark plug wires
- Electrical issues in the ignition system
Symptoms of P2307 Mercury
- Misfires or hesitation during acceleration
- Rough idling or engine stalling
- Decreased fuel efficiency
- Illuminated check engine light
- Difficulty starting the vehicle
How to Fix P2307 Mercury
- Begin by diagnosing the specific cause of the high primary control circuit, which may involve testing the ignition coil 'C', inspecting wiring and connectors, and checking the PCM for any faults.
- If the ignition coil 'C' is found to be faulty, replace it with a new one.
- Repair or replace any damaged wiring or connectors in the ignition system.
- Test the spark plugs and spark plug wires, replacing them if necessary.
- Clear the diagnostic trouble code and test the vehicle to ensure the issue has been resolved.
Cost to Fix P2307 Mercury
The cost of repairing the ignition coil 'C' primary control circuit high code can vary depending on the specific cause of the issue and the parts needed for repair.
