DTC P0961: Pressure Control Solenoid "A" Control Circuit Range/Performance: Notes

DTC detecting condition: 

Immediately at fault recognition

Trouble symptom: 

CAUTION:
  • Use CHECK BOARD when measuring the TCM terminal voltage and resistance.
  • After servicing or replacing faulty parts, perform the last step of the basic diagnostic procedure. Ref. to TRANSMISSION (DIAGNOSTICS)>BASIC DIAGNOSTIC PROCEDURE .

  1. CHECK DTC  .

    Read the DTC using Subaru Select Monitor. Ref. to TRANSMISSION (DIAGNOSTICS)>Diagnostic Trouble Code (DTC) .

    Besides DTC P0961, is DTC P0962 or P0963 displayed?

    Yes  : Perform the diagnosis according to DTCs other than P0961. Ref. to TRANSMISSION (DIAGNOSTICS)>Diagnostic Trouble Code (DTC)>LIST .

    No  : Go to  2.

  2. CHECK LINE PRESSURE SOLENOID (ACTIVE TEST)  .
    1. Turn the ignition switch to ON.
    2. Using the Subaru Select Monitor, perform the active test for line pressure solenoid. Ref. to TRANSMISSION (DIAGNOSTICS)>ACTIVE TEST .

      Is 300 → 500 → 700 mA indicated at the active test, and does [Lin. Sol. Actual Current] follow [Lin. Sol. Set Current]?

      Yes  : Go to  3.

      No  : Go to  4.

  3. CHECK FOR POOR CONTACT  .

    Check for poor contact of harness and connector between TCM and line pressure solenoid.

    Is there poor contact?

    Yes  : Repair the poor contact of harness and connector.

    No  : Recheck the poor contact of harness and connector. Replace the TCM if no fault is found. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR690)>TRANSMISSION CONTROL MODULE (TCM) .

  4. CHECK LINE PRESSURE SOLENOID  .
    1. Turn the ignition switch to OFF.
    2. Disconnect the transmission connector.
    3. Measure the resistance between transmission connector and transmission body.

      Connector & terminal 

      (T19) No. 11 - Transmission body:

      Is the resistance approximately 3.3 - 7.3 Ω? (When cold)

      Yes  : Replace the control valve body. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR690)>CONTROL VALVE BODY .

      No  : Repair or replace the harness.
