How do I fix code P1714 MERCURY?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P1714 MERCURY code
The cost of diagnosing the P1714 MERCURY code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1714 MERCURY Description
The Shift Solenoids “A” through “D” are VFS that vary hydraulic pressure by actuating a hydraulic valve.
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.
