DTC P2759 Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical (Shift Solenoid Valve SLU)


DESCRIPTION

The amount of current flow to the solenoid is controlled by the (*) duty ratio of the TCM output signal. The higher the duty ratio becomes, the higher the lock-up hydraulic pressure becomes during the lock-up operation.

(*) Duty Ratio
The duty ratio is the ratio of the period of continuity in one cycle. For example, if A is the period of continuity in one cycle, and B is the period of non-continuity, then Duty Ratio = A/(A + B) x 100 (%).

DTC No.
DTC Detection Condition
Trouble Area
P2759
Open or short is detected in shift solenoid valve SLU circuit for 1 second or more while driving (1-trip detection logic).
  1. Open or short in shift solenoid valve SLU circuit
  2. Shift solenoid valve SLU
  3. TCM

MONITOR DESCRIPTION

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

  1. Remove the TCM from the transaxle.

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

    Standard resistance:
    Tester Connection
    Specified Condition
    20°C (68°F)
    11 (SLU+) - 5 (SLU-)
    5.0 to 5.6 Ω
  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Check for short:
    Tester Connection
    Specified Condition
    11 (SLU+) - Body ground
    10 kΩ or higher
    5 (SLU-) - Body ground
    10 kΩ or higher


OK
REPLACE TCM

  1. Remove the shift solenoid valve SLU.

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

    Standard resistance:
    Tester Connection
    Specified Condition
    20°C (68°F)
    1 - 2
    5.0 to 5.6 Ω
  1. Connect a positive (+) lead through a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.

    OK:
    The solenoid makes an operating sound.
