P0966 PRESSURE CONTROL SOLENOID B

P0966 PRESSURE CONTROL SOLENOID B

DTC Description

INFOID:0000000010622844

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector (Primary pressure solenoid valve circuit shorted to ground)
• Primary pressure solenoid valve

FAIL-SAFE

• Selector shock is large
• Start  is  slow
• Acceleration is slow
• Lock-up is not performed
• Stop/start system prohibited
• Restart the engine during the stop/start system operation
• Turn OFF the electric oil pump relay

DTC CONFIRMATION PROCEDURE

1.

PREPARATION BEFORE WORK

If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.

>> GO TO 2.

2.

CHECK DTC DETECTION

1.

Start the engine and wait for 5 seconds or more.

2.

Check the first trip DTC.

Is “P0966” detected?

YES

>> Go to 

TM-622, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010622845

1.

CHECK CIRCUIT BETWEEN TCM AND CVT UNIT

1.

Turn ignition switch OFF.

2.

Disconnect TCM connector and CVT unit connector.

3.

Check continuity between TCM harness connector terminal and ground. 

Is the inspection result normal?

YES 

>> GO TO 2.

NO

>> Repair or replace damaged parts.

2.

CHECK PRIMARY PRESSURE SOLENOID VALVE CIRCUIT

Check continuity between CVT unit harness connector terminal and ground.
