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 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 turn on the MIL and store the DTC.

    INSPECT NO. 1 TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLT)


    1. A015739E38

      Disconnect the No. 1 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+) - 5 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      13 (SLT+) - Body ground Always 10 kΩ or higher
      5 (SLT-) - Body ground Always 10 kΩ or higher

    CHECK HARNESS AND CONNECTOR (NO. 1 TRANSMISSION WIRE - ECM)


    1. Disconnect the ECM connector.

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

      Standard Resistance
      Table 2. for LHD
      Tester Connection Condition Specified Condition
      C45-9 (SLT+) - C45-8 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω

    INSPECT SHIFT SOLENOID VALVE SLT


    1. A0155DIE02

      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
