DTC P2714 Pressure Control Solenoid "D" Performance or Stuck OFF


DESCRIPTION

Based on signals from the accelerator position sensor and speed sensors (NT and SP2), the TCM controls the solenoid valve (SLT) using a predetermined 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 and SP2), the TCM calculates the heat level of the friction material, and detects the slip condition of the clutch, etc.

  1. Battery voltage is 9.5 V or higher, engine speed is more than 400 rpm, and the vehicle is driven with the shift lever in D or R (no malfunctions are detected in shift solenoid valve SC1, SC2, SL1, SL2, SL3, SL4, SL5, SLT, SLU, park/neutral position switch assembly, TCM, electronic throttle, knock control sensor, No. 1 ATF temperature sensor, transmission revolution sensors (NT), and CAN communication system)
  2. The engine overruns (neutral status).
  3. Malfunction status is detected 2, 3 or 5 times per trip
  4. 2 trip detection logic

  2. Shift solenoid valve SL1
  3. Shift solenoid valve SL2
  4. Shift solenoid valve SL3
  5. Shift solenoid valve SL4
  6. Shift solenoid valve SL5
  7. Shift solenoid valve SLT
  8. Transmission valve body assembly
  9. Automatic transmission assembly (clutch, brake, gear, etc.)

MONITOR DESCRIPTION

The TCM commands gear shifts by turning the shift solenoid valves on and off. According to the input shaft speed and output shaft speed, the TCM detects the actual gear (1st, 2nd, 3rd, 4th, 5th, 6th, 7th or 8th gear position). When the gear commanded by the actual gear is not the same, the TCM stores this DTC.
NOTICE:
If driving continues under these conditions, the clutches will burn out and the vehicle will no longer be drivable.

INSPECTION PROCEDURE

NOTICE:
Perform registration and/or initialization when parts related to the automatic transmission are replaced (Click here).
HINT:
After performing repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
  1. Start the engine.*1
  2. Drive the vehicle backward with the shift lever in R.*2
  3. Turn the engine switch off.
  4. Perform steps (*1) through (*2) again.
  5. Check for DTCs again (Click here).
1.CHECK DTC OUTPUT (IN ADDITION TO DTC P2714)

  1. Connect the GTS to the DLC3.

  1. Turn the engine switch on (IG).

  1. Turn the GTS on.

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

  1. Read the DTCs using the GTS.
