INSPECT SHIFT SOLENOID VALVE (SLT)

DTC P2716 Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT)


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 cycle 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(%)

MONITOR DESCRIPTION

When an open or short in the linear solenoid valve (SLT) circuit is detected, the ECM interprets this as a fault. The ECM will turn on the MIL and store the DTC.

INSPECTION PROCEDURE

1.INSPECT TRANSMISSION WIRE (SLT)


    Camry. Acv40 Gsv40.U250E Automatic Transaxle.Automatic Transaxle System. Dtc P2716 Pressure Control Solenoid D Electrical (Shift Solenoid Valve Slt)

  1. Disconnect the transmission wire connector from the transaxle.

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

    Standard resistance:
    Tester Connection
    		Specified Condition
    20°C (68°F)
    2 (SLT+) - 8 (SLT-)
    		5.0 to 5.6 Ω

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

    Standard resistance (Check for short):
    Tester Connection
    		Specified Condition
    2 (SLT+) - Body ground
    		10 kΩ or higher
    8 (SLT-) - Body ground


NG
Go to step 3
OK


2.CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)


    Camry. Acv40 Gsv40.U250E Automatic Transaxle.Automatic Transaxle System. Dtc P2716 Pressure Control Solenoid D Electrical (Shift Solenoid Valve Slt)

  1. Connect the transmission wire connector to the transaxle.

  1. Disconnect the ECM connector.

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

    Standard resistance:
    Tester Connection
    		Specified Condition
    20°C (68°F)
    C24-76 (SLT+) - C24-75 (SLT-)
    		5.0 to 5.6 Ω

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

    Standard resistance (Check for short):
    Tester Connection
    		Specified Condition
    C24-76 (SLT+) - Body ground
    		10 kΩ or higher
    C24-75 (SLT-) - Body ground


NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK

REPLACE ECM

3.INSPECT SHIFT SOLENOID VALVE (SLT)


    Camry. Acv40 Gsv40.U250E Automatic Transaxle.Automatic Transaxle System. Dtc P2716 Pressure Control Solenoid D Electrical (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.
