DTC Troubleshooting: P0962 (16-3)

DTC P0962:

Problem in A/T Clutch Pressure Control Solenoid Valve A Circuit

NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information How to Troubleshoot the A/T System.
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
- If DTC P0962 is stored in the PCM, the transmission does not shift to 2nd or 5th gear because of the fail-safe function.

1. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

2. Clear the DTC with the HDS.

3. Check for Pending or Confirmed DTCs with the HDS.

Is DTC P0962 indicated?

YES -

Go to step 4.

NO -

Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between A/T clutch pressure control solenoid valve A and the PCM.

4. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

5. Jump the SCS line with the HDS.

6. Disconnect PCM connector C (49P).

7. Check for continuity between PCM connector terminal C21 and body ground.





Is there continuity?

YES -

Go to step 8.

NO -

Go to step 10.

8. Disconnect the A/T clutch pressure control solenoid valve A connector.

9. Check for continuity between A/T clutch pressure control solenoid valve A connector terminal No. 1 and body ground.





Is there continuity?

YES -

Repair a short to body ground in the wire between PCM connector terminal C21 and A/T clutch pressure control solenoid valve A connector terminal No. 1.

NO -

Faulty A/T clutch pressure control solenoid valve A. Replace the secondary valve body (A/T clutch pressure control solenoid valve A) Secondary Valve Body Replacement.

10. Disconnect the A/T clutch pressure control solenoid valve A connector.

11. Check for continuity between PCM connector terminal C21 and A/T clutch pressure control solenoid valve A connector terminal No. 1.





Is there continuity?

YES -

Go to step 12.

NO -

Repair an open in the wire between A/T clutch pressure control solenoid valve A connector terminal No. 1 and PCM connector terminal C21.

12. Check for continuity between A/T clutch pressure control solenoid valve A connector terminal No. 2 and body ground.





Is there continuity?

YES -

Go to step 13.

NO -

Repair an open in the wire between A/T clutch pressure control solenoid valve A connector terminal No. 2 and body ground (G101), or repair poor body ground (G101).

13. Check for continuity between A/T clutch pressure control solenoid valve A connector terminals No. 1 and No. 2.





Is there continuity?

YES -

Replace the PCM Service and Repair.

NO -

Faulty A/T clutch pressure control solenoid valve A. Replace the secondary valve body (A/T clutch pressure control solenoid valve A) Secondary Valve Body Replacement.
