AUTOMATIC TRANSMISSION SYSTEM(for 1GD-FTV), Diagnostic DTC:P2716

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

DESCRIPTION

The shift 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 current to shift solenoid valve SLT to control hydraulic line pressure coming from the primary regulator valve. Appropriate line pressure assures smooth shifting with varying engine outputs.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory
P2716 Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT) Open or short is detected in shift solenoid valve SLT circuit for 1 second or more while driving (1 trip detection logic).

  • Open or short in shift solenoid valve SLT circuit

  • Shift solenoid valve SLT

  • ECM

 - DTC stored

MONITOR DESCRIPTION

When an open or short in the shift solenoid valve SLT circuit is detected, the ECM interprets this as a fault. The ECM will store the DTC.

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLT)


    1. B003O9BC06
      *a

      Component without harness connected

      (Transmission Wire)

      Disconnect the transmission wire connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      13 (SLT+) - 14 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      13 (SLT+) - Body ground Always 10 kΩ or higher
      14 (SLT-) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

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


    1. B003LKLC06
      *a

      Rear view of wire harness connector

      (to ECM)

      Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      C41-14 (SLT+) - C41-15 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      C41-14 (SLT+) - Body ground Always 10 kΩ or higher
      C41-15 (SLT-) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    OK

  3. INSPECT SHIFT SOLENOID VALVE SLT


    1. B003KJMC15
      *1 Shift Solenoid Valve SLT

      Remove shift solenoid valve SLT.

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

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

    3. Apply 12 V battery voltage to the shift solenoid valve and check that the valve moves and makes an operating noise.

      OK
      Measurement Condition Specified Condition

      • Battery positive (+) with a 21 W bulb → Terminal 1

      • Battery negative (-) → Terminal 2

      		 Valve moves and makes an operating noise
      Result
