DTC P0963: A/T Clutch Pressure Control Solenoid Valve A

WARNING: This page is about a different car, the 2013 Honda Odyssey, 2012 Honda Odyssey, and 2011 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review 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.

Turn the ignition switch to ON (II).
Clear the DTC with the HDS.
Start the engine, and wait for at least 1 second.
Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0963 indicated?

YES -Go to step 8.

NO -Go to step 5.
Select Clutch Pressure Control (Linear) Solenoid Valve A in the Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve A with the HDS.
Does the HDS indicate NORMAL?

YES -Go to step 6.

NO -Go to step 8.
In the Clutch Pressure Control Solenoid Valve Control menu, set A/T Clutch Pressure Control Solenoid Valve A at 0.2 A.
Monitor the OBD status for P0963 in the DTCs MENU with the HDS.
Does the HDS indicate FAILED?

YES -Go to step 8.

NO -If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals between A/T clutch pressure control solenoid valve A and the PCM. If the HDS indicates NOT COMPLETED, go to step 5.
Turn the ignition switch to LOCK (0).
Disconnect the A/T clutch pressure control solenoid valve A connector.
Measure the resistance between A/T clutch pressure control solenoid valve A connector terminals No. 1 and No. 2.

Is there 3-10 Ω?

YES -Go to step 14.

NO -Replace A/T clutch pressure control solenoid valve A (see A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE A AND B REPLACEMENT ), then go to step 11.
Start the engine, and wait for at least 1 second.
Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0963 indicated?

YES -Check for poor connections or loose terminals between A/T clutch pressure control solenoid valve A and the PCM, then go to step 1.

NO -Go to step 13.
Monitor the OBD status for P0963 in the DTCs MENU with the HDS.
Does the HDS indicate PASSED?

YES -Troubleshooting is complete. If any other Pending or Confirmed DTCs were indicated in step 12, go to the INDICATED DTC'S TROUBLESHOOTING .

NO -If the HDS indicates FAILED, check for poor connections or loose terminals between A/T clutch pressure control solenoid valve A and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, go to step 11.
Reconnect all connectors.
Update the PCM if it does not have the latest software (see PCM UPDATE ), or substitute a known-good PCM (see SUBSTITUTING THE PCM ).
Start the engine, and wait for at least 1 second.
Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0963 indicated?

YES -Check for poor connections or loose terminals between A/T clutch pressure control solenoid valve A and the PCM. If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ), then go to step 16. If the PCM was substituted, go to step 1.

NO -Go to step 18.
Monitor the OBD status for P0963 in the DTCs MENU with the HDS.
Does the HDS indicate PASSED?

YES -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM (see PCM REPLACEMENT ). If any other Pending or Confirmed DTCs were indicated in step 17, go to the INDICATED DTC'S TROUBLESHOOTING .

NO -If the HDS indicates FAILED, check for poor connections or loose terminals between A/T clutch pressure control solenoid valve A and the PCM. If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ), then go to step 16. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 16.
