AUTOMATIC TRANSMISSION SYSTEM, Diagnostic DTC:P0965, P0966, P0967

DTC Code DTC Name
P0965 Pressure Control Solenoid "B" Performance (SL2 Solenoid)
P0966 Pressure Control Solenoid "B" Control Circuit Low (Shift Solenoid Valve DS2)
P0967 Pressure Control Solenoid "B" Control Circuit High (Shift Solenoid Valve DS2)

DESCRIPTION

Based upon a signal from the TCM, the combination of shift solenoid valves (S1, S2, S3, S4, SR, SL1, SL2) changes the gear position from 1st to 6th. As a fail-safe function, if the solenoid valve system is open or shorted, the TCM cuts power to all solenoids, leaving just the mechanical hydraulic circuit, requiring manual shifting.

DTC No.

MONITOR DESCRIPTION

This DTC indicates an open, short or feedback stuck in the shift solenoid valve SL2 circuit. The TCM commands gear shifts by turning the shift solenoid valves "ON/OFF". When there is an open or short circuit in any shift solenoid valve circuit, the TCM detects the problem and illuminates the MIL and stores the DTC.

Tech Tips


  • The shift solenoid valve SL2 is turned on/off normally when the shift lever is in the D position:

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SL2)


    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
      L4-14(SL2+) - L4-7(SL2-) 20°C(68°F) 5.0 to 5.6 Ω
      L4-14(SL2+) - Body ground Always 10 kΩ or higher
      L4-7(SL2-) - Body ground Always 10 kΩ or higher
    3. Connect the L4 transmission wire connector.


    NG
    OK
  2. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - TCM)


    1. Disconnect the TCM connector.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      A18-5(SL2+) - A18-11(SL2-) 20°C(68°F) 5.0 to 5.6 Ω
      A18-5(SL2+) - Body ground Always 10 kΩ or higher
      A18-11(SL2-) - Body ground Always 10 kΩ or higher
    3. Connect the TCM connector.


    NG
    OK
