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

DESCRIPTION

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 Open or short is detected in the 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

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 illuminate the MIL and store the DTC.

    INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLT)


    1. A003DSGE04

      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
      2 (SLT+) - 6 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      2 (SLT+) - Body ground Always 10 kΩ or higher
      6 (SLT-) - Body ground Always 10 kΩ or higher
      Table 1. Text in Illustration

    CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)


    1. A003BS9E07

      Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D97-54 (SLT+) - D97-53 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      D97-54 (SLT+) - Body ground Always 10 kΩ or higher
      D97-53 (SLT-) - Body ground Always 10 kΩ or higher

    INSPECT SHIFT SOLENOID VALVE SLT


    1. A003I9EE03

      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 2

      • Battery negative (-) → Terminal 1

      		 Valve moves and makes an operating noise
