DTC P0967: Problem in A/T Clutch Pressure Control Solenoid Valve B

NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information. How to Troubleshoot A/T Systems

- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

1. Clear the DTC with the HDS.

2. Check that DTC P0967 recurs.

Is DTC P0967 indicated?
YES - Go to step 6.

NO - Go to step 3.


3. Select Clutch Pressure Control (Linear) Solenoid Valve B in the Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve B with the HDS.

Does the HDS indicate NORMAL?
YES - Go to step 4.

NO - Go to step 6.


4. In the Clutch Pressure Control Solenoid Valve Control menu, select A/T Clutch Pressure Control Solenoid Valve B at 0.2 A.

5. Monitor the OBD status for P0967 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

Does the HDS indicate FAILED?
YES - Go to step 6.

NO - If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between A/T clutch pressure control solenoid valve B and the PCM. If the HDS indicates NOT COMPLETED, go to step 3.


6. Turn the ignition switch to LOCK (0).

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

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

Is there 3-10 Ohms?
YES - Go to step 9.

NO - Replace A/T clutch pressure control solenoid valve B, A/T Clutch Pressure Control Solenoid Valve A and B Replacement then go to step 15.






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

Is there continuity?
YES - Go to step 10.

NO - Repair open in the wire between the A/T clutch pressure control solenoid valve B and body ground (G101), or repair poor body ground (G101), then go to step 15.






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

11. Update the A/T software in the PCM if it does not have the latest software, PCM Update or substitute a known-good PCM. Initial Inspection and Diagnostic Overview

12. Start the engine, and wait for at least 1 second.

13. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0967 indicated?
YES - If the PCM was updated, substitute a known-good PCM, Initial Inspection and Diagnostic Overview then recheck. If the PCM was substituted, go to step 1.

NO - Go to step 14.


14. Monitor the OBD status for P0967 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

Does the HDS indicate PASSED?
YES - If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM. Service and Repair If any other DTCs were indicated on step 13, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, check for poor connections and loose terminals between A/T clutch pressure control solenoid valve B and the PCM. If the PCM was updated, substitute a known-good PCM, Initial Inspection and Diagnostic Overview then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 12.


15. Connect the A/T clutch pressure control solenoid valve B connector.

16. Clear the DTC with the HDS.

17. Start the engine, and wait for at least 1 second.

18. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0967 indicated?
YES - Check for poor connections and loose terminals between A/T clutch pressure control solenoid valve B and the PCM, then go to step 1.

NO - Go to step 19.


19. Monitor the OBD status for P0967 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

Does the HDS indicate PASSED?
YES - Troubleshooting is complete. If any other DTCs were indicated on step 18, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, check for poor connections and loose terminals between A/T clutch pressure control solenoid valve B and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, go to step 17.
