DTC P0965: Pressure Control Solenoid "B" Control Circuit Range/Performance: Notes

DTC detecting condition: 

Immediately at fault recognition

Trouble symptom: 

• Engine speed increases abruptly, and can not accelerate.
• Excessive slippage is felt.
  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 P0965, is DTC P0720, P0966, P0967, or P2751 displayed?

   Yes:  Perform the diagnosis according to DTCs other than P0965. Ref. to TRANSMISSION (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST .

   No:  Go to  2.

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

   Is 300 - 500 - 700 mA indicated at the active test, and does [Actual Forward & Reverse Linear Solenoid Current] follow [Commanded Forward & Reverse Linear Solenoid 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 F & R 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 F & R SOLENOID. 
   1. Turn the ignition switch to OFF.
   2. Disconnect the transmission connector.
   3. Measure the resistance between transmission connector and transmission body.

      Connector and terminal. 

      (T19) No. 12 - Transmission body:

   Is the resistance approximately 4 - 6 Ω? (When cold)

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

   No:  Repair or replace the harness.
