AUTOMATIC TRANSMISSION SYSTEM, Diagnostic DTC:P2714

DTC Code DTC Name
P2714 Pressure Control Solenoid "D" Performance (Shift Solenoid Valve SLT)

DESCRIPTION

Based on signals from the accelerator position sensor and speed sensors (NC3, SP2 and NT), the TCM controls the solenoid valve (SLT) using a predetermined the current. As a result, the line pressure is adjusted to a pressure that is appropriate for the throttle angle and engine output. Based on the rotation speed indicated by the transmission speed sensors (NT, NC3 and SP2), the TCM calculates the heat level of the friction material, and detects the slip condition of the clutch, etc.

DTC Detection Condition


  1. Diagnosis Condition

  2. Malfunction Status

  3. Other

 Trouble Area
P2714

  1. ECT is 40°C (104°F) or higher, ATF temperature is -10°C (14°F) or higher, and the vehicle is driven with the shift lever in D (no malfunctions are detected in shift solenoid valve SL1, 2, 3, 4 and 5, SR, SLT, speed sensors (NT, NC3, SP2), engine coolant temperature sensor, oil temperature sensor, knock control sensor, electronic throttle, or CAN2)

  2. - Engine overruns at an engine torque that is above the set engine torque of each gear

    - Clutch is judged to be slipping, and the friction material is overheated beyond the specified threshold

  3. 2 trip detection logic

  • Shift solenoid valve SL1

  • Shift solenoid valve SL2

  • Shift solenoid valve SL3

  • Shift solenoid valve SL4

  • Shift solenoid valve SL5

  • Shift solenoid valve SLT

  • Valve body assembly

  • Torque converter clutch assembly

  • Automatic w/transfer transmission assembly

MONITOR DESCRIPTION

The TCM calculates the amount of heat absorbed by the friction material based on the difference in revolution (clutch slippage) between the turbine and output shaft. The TCM illuminates the MIL and stores this DTC when the amount of heat absorption exceeds the specified value.

When shift solenoid valve SLT remains on, oil pressure goes down and clutch engagement force decreases.

Note

If you continue driving under these conditions, the clutch will burn out and the vehicle will no longer be drivable.

INSPECTION PROCEDURE

PROCEDURE


  1. CHECK DTC OUTPUT (IN ADDITION TO DTC P0746, P0771, P0776, P0796, P2714, P2808 AND P2817)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the intelligent tester on.

    4. Enter the following menus: Powertrain / ECT / Trouble Codes.

    5. Read the DTCs using the intelligent tester.

      Result
      Display (DTC output) Proceed to
      P2714 and one or more of the following DTCs are output: P0746, P0771, P0776, P0796, P2808, P2817 A
      Only P2714 is output B
      P0746, P0771, P0776, P0796, P2714, P2808 or P2817 and other DTCs are output C

      Tech Tips

      If any other codes besides P0746, P0771, P0776, P0796, P2714, P2808 and P2817 are output, perform troubleshooting for those DTCs first.

  3. INSPECT SHIFT SOLENOID VALVE SLT


    1. A01GNU1E04

      Remove shift solenoid valve SLT Click here.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      Terminal 1 of shift solenoid valve SLT - Terminal 2 20°C (68°F) 5.0 to 5.6 Ω

    3. Connect the battery's positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector. Then check that the valve moves and makes an operating noise.

      OK
      Valve moves and makes operating noise.
