AUTOMATIC TRANSAXLE SYSTEM, Diagnostic DTC:P2716

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

DESCRIPTION

A0055CBE02
*1 Hydraulic Pressure
*2 Current

Shift solenoid valve SLT controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and vehicle speed sensor. The ECM adjusts the current to shift solenoid valve SLT to control the hydraulic line pressure coming from the primary regulator valve. Appropriate line pressure assures smooth shifting with varying engine outputs.

DTC Code DTC Detection Condition Trouble Area
P2716 The duty cycle to shift solenoid valve SLT is 100% (1 trip detection logic).
  • Open or short in shift solenoid valve SLT circuit

  • Shift solenoid valve SLT

  • ECM

MONITOR DESCRIPTION

When an open or short in the shift solenoid valve SLT circuit is detected, the ECM interprets this as a fault. Then the ECM illuminates the MIL and stores the DTC.

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLT)


    1. A0055R6E17
      Text in Illustration
      *1

      Component without harness connected

      (Transmission Wire)

      Disconnect the B19 transmission wire connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      2 (SLT+) - 7 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      2 (SLT+) - Body ground Always 10 kΩ or higher
      7 (SLT-) - Body ground Always 10 kΩ or higher

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

      Front view of wire harness connector

      (to ECM)

      Disconnect the B39 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      B39-54 (SLT+) - B39-53 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      B39-54 (SLT+) - Body ground Always 10 kΩ or higher
      B39-53 (SLT-) - Body ground Always 10 kΩ or higher

    OK
    NG
  3. INSPECT SHIFT SOLENOID VALVE SLT


    1. A0054M6E01
      Text in Illustration
      *1

      Component without harness connected

      (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

    OK
    NG
