DTC P0971: Problem in A/T Clutch Pressure Control Solenoid Valve C2006 Model
NOTE:
^ Record all freeze data and review General Troubleshooting Information before you troubleshoot.
^ 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 P0971 recurs.
Is DTC P0971 indicated?
YES - Go to Step 6.
NO - Go to step 3.
3. Choose Clutch Pressure Control Solenoid Control in Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve C with the HDS.
4. Set A/T clutch pressure control solenoid valve C to 0.2 A in Clutch Pressure Control Solenoid Control menu.
5. Monitor the OBD status for P0971 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate FAILED?
YES - Go to Step 6.
NO - If the tester indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at A/T clutch pressure control solenoid valve C and PCM. If the tester indicates NOT COMPLETED, return to step 3 and recheck.
6. Turn the ignition switch OFF.
7. Disconnect the A/T clutch pressure control solenoid valve C connector.
8. Measure the resistance between the A/T clutch pressure control solenoid valve C connector terminals.
Is there 3 - 10 Ohms?
YES - Go to Step 9.
NO - Replace A/T clutch pressure control solenoid valve C, then go to Step 10.
9. Check for continuity between A/T clutch pressure control solenoid valve A connector terminal No. 2 and body ground.
Is there continuity?
YES - Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.
NO - Repair open in the wire between A/T clutch pressure control solenoid valve C and ground (G151), or repair poor ground (G151), then go to Step 10.
10. Clear the DTC with the HDS.
11. Test-drive the vehicle for several minutes in the D position through all five gears.
12. Monitor the OBD status for P0971 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate PASSED?
YES - Troubleshooting is complete.
NO - Return to step 6 and recheck.
