P0966

NOTE:

Check that the following conditions are satisfied when using this procedure.

- Battery voltage > 10.5 V

1) Turn ignition switch to ON position for 10 sec.

P0967

NOTE:

- If DTC other than aimed DTC are previously detected in DTC confirmation procedure, be sure to troubleshoot DTC previously detected.
- Check that the following conditions are satisfied when using this procedure.

- Battery voltage > 10.5 V

2) Turn ignition switch to ON position for 10 sec.

DTC Troubleshooting



1.
Was "CVT System Check" performed?
YES
Go to Step 2.
NO
Go to CVT System Check.

2. Secondary pressure control solenoid valve drive circuits check

Turn off ignition switch and disconnect TCM and solenoid connectors.
Check for proper terminal connection to TCM and solenoid connectors.
If connections are OK, check that secondary pressure control solenoid valve drive circuit (A3) is as follows.
- Wiring harness resistance of secondary pressure control solenoid valve circuit is less than 1 ohms.
- Insulation resistance of secondary pressure control solenoid valve drive circuit is infinity between solenoid connector and vehicle body ground.
- Insulation resistance of wire harness is infinity between secondary pressure control solenoid valve drive circuit terminal and each terminal at solenoid connector.
- Circuit voltage of secondary pressure control solenoid valve drive circuit 0 - 1 V with ignition switch ON position.

Is it in good condition?
YES
Go to Step 3.
NO
Repair or replace defective wire harness.

3. Secondary pressure control solenoid valve check

Check resistance of secondary pressure control solenoid valve. Testing and Inspection

Is it in good condition?
YES
Substitute a known-good TCM and recheck.
NO
Replace secondary pressure control solenoid valve (CVT assembly).
