Title: UA80E (AUTOMATIC TRANSMISSION / TRANSAXLE): AUTOMATIC TRANSAXLE SYSTEM: P27137F; Pressure Control Solenoid "D" Actuator Stuck Off; 2019 - 2020 MY Sienna [08/2018 -        ]

DTC

P27137F

Pressure Control Solenoid "D" Actuator Stuck Off

DESCRIPTION

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

DTC No.

  1. Engine coolant temperature is 40°C (104°F) or higher, ATF temperature is -10°C (14°F) or higher, and the vehicle is being driven with the shift lever in D (no malfunctions are detected in the shift solenoid valves SL1, SL2, SL3, SL4, SL5, SL6, SL, SLU and SLT, transmission revolution sensors (NT and NC), coolant temperature sensor, oil temperature sensor, knock sensor, electronic throttle or CAN2)
  2. The transmission revolution sensor (NT) value exceeds the specified speed for each gear.
  3. Malfunction status continues for 0.5 seconds or more
  4. 2-trip detection logic

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 shift solenoid valve SLT 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 2017 - 2020 MY Sienna [08/2016 -        ]; UA80E (AUTOMATIC TRANSMISSION / TRANSAXLE): AUTOMATIC TRANSAXLE SYSTEM: DTC CHECK / CLEAR

  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch to ON and turn the Techstream on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
