DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory
P2759 Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical (Shift Solenoid Valve SLU) An open or short is detected in the shift solenoid valve SLU circuit for 1 second or more while driving (1-trip detection logic).

  • Open or short in shift solenoid valve SLU circuit

  • Shift solenoid valve SLU

  • TCM

 Comes on DTC stored

MONITOR DESCRIPTION

When an open or short in the shift solenoid valve SLU circuit is detected, the TCM determines there is a malfunction. The TCM will turn on the MIL and store the DTC.

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLU)


    1. A01QOXMC20
      *a

      Component without TCM connected

      (Transmission Wire)

      Remove the TCM.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      11 (SLU+) - 5 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      11 (SLU+) - Body ground Always 10 kΩ or higher
      5 (SLU-) - Body ground Always 10 kΩ or higher
      11 (SLU+) - All other terminals except 5 (SLU-) Always 10 kΩ or higher
      5 (SLU-) - All other terminals except 11 (SLU+) Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

  2. INSPECT SHIFT SOLENOID VALVE SLU


    1. A01QTPTC16
      *1 Shift Solenoid Valve SLU

      Remove shift solenoid valve SLU.

    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
      Proceed to
      OK
      NG

    OK
