Lexus ES: Pressure Control Solenoid "D" Actuator Stuck Off (P27137F)

Lexus ES (XZ10) Service Manual / Drivetrain / Ub80f (automatic Transmission / Transaxle) / Automatic Transaxle System / Pressure Control Solenoid "D" Actuator Stuck Off (P27137F)

DESCRIPTION

Based on signals from the accelerator position sensor and transmission revolution sensors (NT and NC), the ECM controls the solenoid (SLT) valve 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 signals from the transmission revolution sensors (NT and NC), the ECM calculates the heat level of the friction material, and detects clutch slippage, etc.

Pressure Control Solenoid "D" Actuator Stuck Off

All of the following conditions are met (2-trip detection logic):

  • Engine coolant temperature is 40°C (104°F) or higher.
  • ATF temperature is -10°C (14°F) or higher.
  • The vehicle is being driven with the shift lever in D.
  • No malfunctions are detected in the solenoid (SL1, SL2, SL3, SL4, SL5, SL6, SL, SLU and SLT) valves, transmission revolution sensors (NT and NC), coolant temperature sensor, oil temperature sensor, knock sensor, crankshaft position sensor circuits, electronic throttle or CAN communication system.
  • The transmission revolution sensor (NT) value exceeds the specified speed for each gear for 0.5 seconds or more.
  • Solenoid (SL1) valve
  • Solenoid (SL2) valve
  • Solenoid (SL3) valve
  • Solenoid (SL4) valve
  • Solenoid (SL5) valve
  • Solenoid (SL6) valve
  • Solenoid (SL) valve
  • Solenoid (SLU) valve
  • Solenoid (SLT) valve
  • Transmission valve body assembly
  • Automatic transaxle assembly (clutch, brake, gear, etc.)

SAE Code:

P2714

MONITOR DESCRIPTION

The ECM calculates the amount of heat absorbed by the clutch discs and brake discs based on the difference in speed (clutch slippage) between the turbine (input) and output shaft. If the amount of heat absorption exceeds the specified value, the ECM will illuminate the MIL and store this DTC.

If the solenoid (SLT) valve is stuck ON, the line pressure and clutch engagement force will decrease.

NOTICE:

If driving continues under these conditions, the clutches will burn out and the vehicle will no longer be drivable.

CONFIRMATION DRIVING PATTERN

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.

HINT:

  • After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
  • When clearing the permanent DTCs, refer to the Clear Permanent DTC procedure.

    Click here

  1. Connect the Techstream to the DLC3.
  2. Turn the engine switch on (IG) and turn the Techstream on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the engine switch off and wait for 2 minutes or more.
  5. Turn the engine switch on (IG) and turn the Techstream on.
  6. Start the engine.
  7. Perform the D Position Shift Test inspection in Road Test. [*1]

    HINT:

    [*1] : Normal judgment procedure.

    The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

  8. Stop the vehicle.
  9. Enter the following menus: Powertrain / Transmission / Utility / All Readiness.
  10. Input the DTC: P27137F.
  11. Check the DTC judgment result.

    Techstream Display

    Description

    NORMAL
    • DTC judgment completed
    • System normal

    ABNORMAL
    • DTC judgment completed
    • System abnormal

    INCOMPLETE
    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    N/A
    • Unable to perform DTC judgment
    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    HINT:

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
