P1714 Mercury Code - Shift Solenoid 'A' Fault
Quick Answer
The Shift Solenoids "A" through "D" are VFS that vary hydraulic pressure by actuating a hydraulic valve. Common causes include Faulty Shift Solenoid 'A', Shift Solenoid 'A' harness is open or shorted, Shift Solenoid 'A' circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1714 Mercury Description
The Transmission Control Unit (TCU) applies variable current to the shift solenoid which varies the pressure in the hydraulic circuit to the regulator and latch valves of the clutch that in controls.
Shift Solenoid A (SSA) and Shift Solenoid C (SSC) use proportional operation. As the current from the TCU decreases, the pressure from the solenoids decreases. As the current from the TCU increases, the pressure from the solenoid decreases.
With zero current, SSA and SSC fully close the hydraulic valves which apply zero amount of hydraulic pressure to the regulator and latch valves of the clutch that it control and release the clutch.With maximum current to the solenoid, the hydraulic valves fully open for maximum pressure to the regulator and latch valves to apply the clutch.
Shift Solenoid B (SSB) and Shift Solenoid D (SSD) use inverse operation. As current from the TCU decreases, the pressure from the solenoid increases. As current from the TCU increases, the pressure from the solenoid decreases.
With zero current, SSB and SSD fully open the hydraulic valves which apply maximum hydraulic pressure to the regulator and latch valves to apply the clutch that it controls. With maximum current to the solenoids, the hydraulic valve fully closes to apply zero amount of hydraulic pressure to the regulator and latch valves of the clutch that it controls and release the clutch.
What are the Possible Causes of the DTC P1714 Mercury?
- Faulty Shift Solenoid 'A'
- Shift Solenoid 'A' harness is open or shorted
- Shift Solenoid 'A' circuit poor electrical connection
How to Fix the DTC P1714 Mercury?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P1714 Mercury code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P1714 Mercury Code
1. What does the OBDII code P1714 mean on a Mercury vehicle?
P1714 indicates a fault with Shift Solenoid 'A' in the transmission, which may cause shifting issues or abnormal transmission operation.
2. What are common symptoms of the P1714 code in a Mercury?
Symptoms may include harsh or delayed shifting, stuck gears, transmission slipping, or the check engine light being illuminated.
3. What causes the P1714 code to appear on a Mercury vehicle?
Common causes include a faulty shift solenoid 'A', damaged wiring or connectors, low transmission fluid, or internal transmission issues.
4. Can driving with the P1714 code damage my Mercury's transmission?
Yes, continuing to drive with this code can lead to further transmission damage and more costly repairs if not addressed promptly.
5. How is the P1714 code diagnosed on a Mercury?
A mechanic will use a scan tool to verify the code, inspect wiring and connectors, check the transmission fluid level, and test the shift solenoid for proper operation.
6. How do I fix the P1714 code on my Mercury?
Repairs may involve replacing the faulty shift solenoid 'A', repairing damaged wiring, topping off or replacing the transmission fluid, or addressing internal transmission issues.
7. How much does it cost to fix the P1714 code on a Mercury?
The cost depends on the exact repair needed. Replacing a shift solenoid typically costs $150-$400, while more extensive transmission repairs could be significantly higher.
8. Can low transmission fluid cause the P1714 code?
Yes, low or contaminated transmission fluid can lead to insufficient pressure for the solenoid to function, triggering the P1714 code.
9. Is the P1714 code specific to Mercury vehicles?
While the P1714 code can appear on other makes, the specific diagnostic and repair procedures may vary for Mercury vehicles.
10. Can I clear the P1714 code without fixing the problem?
Clearing the code without addressing the underlying issue may temporarily turn off the check engine light, but the code will likely return if the problem persists.
