Pressure Control Solenoid "D" Circuit Short to Ground or Open

While the engine is running, a short to ground or open is detected in the solenoid (SLT) valve circuit for 1 second (1-trip detection logic).
  • Solenoid (SLT) valve
  • Transmission wire
  • Harness and connector
  • ECM

Comes on

DTC stored

SAE Code:

P2720

MONITOR DESCRIPTION

When an open or short to ground in the solenoid (SLT) valve circuit is detected, the ECM will determine that there is a malfunction, illuminate the MIL and store this DTC.

CONFIRMATION DRIVING PATTERN

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 2020 - 2024 MY Camry [03/2020 -        ]; UB80F (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).
  4. Turn the ignition switch off and wait for 2 minutes or more.
  5. Turn the ignition switch to ON and turn the Techstream on.
  6. Start the engine.
  7. Wait for 2 seconds or more with the engine running. [*1]

    HINT:

    [*1] : Normal judgment procedure.

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

  8. Enter the following menus: Powertrain / Transmission / Utility / All Readiness.
  9. Input the DTC: P271314.
  10. 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.
