DTC P0796: A/T Clutch Pressure Control Solenoid Valve C Stuck OFFDTC P0797: A/T Clutch Pressure Control Solenoid Valve C Stuck ON
NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information.
1. Warm up the engine to normal operating temperature (the radiator fan comes on).
2. Make sure that the transmission is filled to the proper level, and check for fluid leaks.
3. Drain the ATF through a strainer. Inspect the strainer for metal debris or excessive clutch material.
Does the strainer have metal debris or excessive clutch material?
YES - Replace the transmission, then go to step 11.
NO - Replace the ATF, then go to step 4.
4. Clear the DTC with the HDS.
5. Start the engine. With the brake pedal pressed, shift to D, and wait for at least 3 seconds. Shift to R, wait for at least 3 seconds, then reverse the vehicle for at least 3 seconds. Slow down and stop the wheels.
6. Turn the ignition switch to LOCK (0). Repeat step 5, then go to step 7.
7. Monitor the OBD STATUS for P0796 or P0797 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the HDS indicate FAILED?
YES - Go to step 8.
NO - Intermittent failure, the system is OK at this time. If the HDS indicates NOT COMPLETED, return to step 5 and recheck.
8. Clear the DTC with the HDS.
9. Select Clutch Pressure Control (Linear) Solenoid C in the Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve C with the HDS.
Does the HDS indicate NORMAL?
YES - Intermittent failure, the system is OK at this time.
NO - Follow the instructions indicated on the HDS by the test result, but if the HDS has not determined the cause of the failure, go to step 10. If any part is replaced, go to step 11.
10. Inspect A/T clutch pressure control solenoid valve C.
Does A/T clutch pressure control solenoid valve C work properly?
YES - Repair the hydraulic system related with shift valve C, or replace the transmission, then go to step 11.
NO - Replace A/T clutch pressure control solenoid valve C, then go to step 11.
11. Clear the DTC with the HDS.
12. Test-drive the vehicle with the shift lever in D, and let the transmission shift through all five gears, then slow down to a stop.
13. Turn the ignition switch to LOCK (0). Repeat step 12, then go to step 14.
14. Monitor the OBD STATUS for P0796 or P0797 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the HDS indicate PASSED?
YES - Troubleshooting is complete.
NO - Return to step 11 and recheck. If the HDS indicates NOT COMPLETED, return to step 12 and recheck.
