DTC P0962: Problem in A/T Clutch Pressure Control Solenoid Valve A Circuit

WARNING: This page is about a different variant/trim than selected.
NOTE:
  • Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION  ).
  • 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. Check for a blown No. 10 (10 A) fuse in the driver's under-dash fuse/relay box.

    Is the No. 10 (10 A) fuse OK? 

    YES  - Go to step 6.

    NO  - Repair a short to body ground in the wire between PCM connector terminal A1 and the driver's under-dash fuse/relay box.

  6. Jump the SCS line with the HDS.
  7. Disconnect PCM connectors A (49P).
  8. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
  9. Measure the voltage between PCM connector terminals A1 and body ground.

    Is there battery voltage? 

    YES  - Go to step 10.

    NO  - Repair an open in the wire between PCM connector terminal A1 and the driver's under-dash fuse/relay box.

  10. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
  11. Jump the SCS line with the HDS.
  12. Disconnect PCM connector C (49P).
  13. Check for continuity between PCM connector terminal C21 and body ground.

    Is there continuity? 

    YES  - Go to step 14.

    NO  - Go to step  16.

  14. Disconnect the A/T clutch pressure control solenoid valve A connector.
  15. 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.

    NO  - Faulty A/T clutch pressure control solenoid valve A. Replace the secondary valve body (A/T clutch pressure control solenoid valve A) (see SECONDARY VALVE BODY REPLACEMENT  ).

  16. Disconnect the A/T clutch pressure control solenoid valve A connector.
  17. 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 18.

    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.

  18. 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 19.

    NO  - Repair an open in the wire between the A/T clutch pressure control solenoid valve A connector and body ground (G101) (see CONNECTOR TO FUSE/RELAY BOX INDEX ), or repair poor body ground (G101).

  19. Measure the resistance between A/T clutch pressure control solenoid valve A connector terminals No. 1 and No. 2.

    Is there 4.7-5.9 Ω? 

    YES  - Replace the PCM (see ECM/PCM REPLACEMENT ).

    NO  - Faulty A/T clutch pressure control solenoid valve A. Replace the secondary valve body (A/T clutch pressure control solenoid valve A) (see SECONDARY VALVE BODY REPLACEMENT  ).
