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


SYSTEM DESCRIPTION

The linear solenoid valve (SLT) controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and the vehicle speed sensor. The ECM adjusts the duty ratio (*) of the SLT solenoid valve to control hydraulic line pressure coming from the primary regulator valve. Appropriate line pressure assures smooth shifting with varying engine outputs.
(*): Duty Ratio
The duty ratio is the ratio of the period of continuity in one cycle. For example, if A is the period of continuity in one cycle, and B is the period of non-continuity, then
Duty Ratio= A/(A+B) x 100(%)

DTC No.
DTC Detection Condition
Trouble Area
P2714
ECM detects a malfunction on SLT (ON side) according to the revolution difference of the turbine, intermediate and the output shaft, and also by the oil pressure. (2-trip detection logic)
  1. Shift solenoid valve SLT remains closed
  2. Valve body is blocked
  3. Automatic transaxle (clutch, brake or gear, etc.)

MONITOR DESCRIPTION

In any forward position, when the difference between the revolutions of the turbine, Intermediate and output shaft exceeds the specified value (varies with Intermediate, output speed) determined by the ECM, the ECM illuminates the MIL and outputs the DTC.
When shift solenoid valve SLT remains on, the oil pressure goes down and the clutch engagement force decreases.
NOTICE:
If you continue driving under these conditions, the clutch will burn out and the vehicle will no longer be drivable.

INSPECTION PROCEDURE

1.CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P2714)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to the ON position.

  1. Turn on the tester.

  1. Select the item "Powertrain / ECT / DTC / Current or Pending".

  1. Read the DTCs using the intelligent tester.

    Result:

    Display (DTC output)
    		Proceed to
    Only "P2714" is output
    		A
    "P2714" and other DTCs
    		B
    HINT:
    If any other codes besides "P2714" are output, perform troubleshooting for those DTCs first.

2.INSPECT SHIFT SOLENOID VALVE SLT


    Camry. Acv40 Gsv40.U250E Automatic Transaxle.Automatic Transaxle System. Dtc P2714 Pressure Control Solenoid D Performance (Shift Solenoid Valve Slt)

  1. Remove the shift solenoid valve SLT.

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

    Standard resistance:
    Tester Connection
    		Specified Condition
    20°C (68°F)
    1-2
    		5.0 to 5.6 Ω

  1. Connect the positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.

    OK:
    The solenoid makes an operating sound.
