DTC P0963: CVT Drive Pulley Pressure Control Valve Circuit High Voltage2005 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 P0963 recurs.
Is DTC P0963 indicated?
YES- Go to step 3.
NO- Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the solenoid harness connector, TCM and the CVT drive pulley pressure control valve.
3. Turn the ignition switch OFF.
4. Disconnect the solenoid harness connector (8P).
5. Measure the resistance between solenoid harness connector (8P) terminals No. 3 and No. 7.
Is there 3.8 - 6.8 ohms?
YES- Go to step 6.
NO- Remove the lower valve body, and check for an open or a short in the solenoid harness. If the wire is OK, replace the CVT drive pulley pressure control valve, then go to step 11.
6. Disconnect TCM connector A (26P).
7. Turn the ignition switch ON (II).
8. Check for the voltage between TCM connector terminals A3 and body ground, and between A16 and body ground.
Is there voltage?
YES- Repair short to power in the wires between TCM connector terminals A3, A16, and the solenoid harness connector.
NO- Go to step 9.
9. Check for continuity between TCM connector terminals A3 and body ground, and between A16 and body ground.
Is there continuity?
YES- Repair short to ground in the wire between TCM connector terminals A3 and the solenoid harness connector, or between A16 and the connector.
NO- Go to step 10.
10. Check for continuity between TCM connector terminals A4 and body ground, A13 and body ground, A17 and body ground, and between A26 and body ground.
Is there continuity?
YES- Substitute a known-good TCM, then recheck. If the symptom/indication goes away with a known-good TCM, replace the original TCM.
NO- Repair open in the wires between TCM connector terminals A4, A13, A17, A26, and ground (G101), or repair poor ground (G101).
11. Clear the DTC with the HDS.
12. Check that DTC P0963 recurs.
Is DTC P0963 indicated?
YES- Return to step 3 and recheck.
NO- The problem has been corrected.
