AUTOMATIC TRANSMISSION SYSTEM, Diagnostic DTC:P2762, P2763, P2764

DTC Code DTC Name
P2762 Torque Converter Pressure Control Solenoid Circuit Performance (SLU / DSU Solenoid)
P2763 Torque Converter Clutch Pressure Control Solenoid Control Circuit High (Shift Solenoid Valve DSU)
P2764 Torque Converter Clutch Pressure Control Solenoid Control Circuit Low (Shift Solenoid Valve DSU)

DESCRIPTION

The shift solenoid valve SLU is controlled by the duty ratio as determined in advance by the TCM. In this way, it carries out lock-up and flex lock-up control.

DTC No.

P2764

  1. Not learning control prohibited status

    Not malfunction with the shift solenoid valve SLU/DSU circuit performance.

  2. 1 second or more has elapsed after turning shift solenoid valve SLU on.

    The shift solenoid valve SLU operational feedback voltage is 0.257 V or more.

  • Harness and connector

  • TCM

MONITOR DESCRIPTION

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

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SLU)


    1. Disconnect the L4 transmission wire connector.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      L4-12(SLU+) - L4-5(SLU-) 20°C(68°F) 5.0 to 5.6 Ω
      L4-12(SLU+) - Body ground Always 10 kΩ or higher
      L4-5(SLU-) - Body ground Always 10 kΩ or higher

    3. Connect the L4 transmission wire connector.
