P0964 Meaning
The P0964: Pressure Control Solenoid ‘B’ Control Circuit/Open code indicates that there is an open circuit preventing the pressure control solenoid ‘B’ from functioning properly. The solenoid is responsible for managing hydraulic pressure in the transmission, and any failure in this circuit can lead to poor transmission performance, including rough shifting or slippage.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional fault codes that may provide further details about the issue. | OBD-II Scanner |
| Test for Circuit Continuity | Use a multimeter to check for continuity in the pressure control solenoid ‘B’ circuit. Ensure that there is no open circuit. | Multimeter |
| Inspect Wiring and Connectors | Visually inspect the wiring and connectors for damage, corrosion, or loose connections in the pressure control solenoid ‘B’ circuit. | Flashlight, Multimeter |
| Test the Solenoid | Use a diagnostic tool to test the pressure control solenoid ‘B’ for proper operation. If the solenoid is faulty, replace it. | Diagnostic Tool, Replacement Solenoid |
| Clear the Code and Test Drive | After completing repairs, clear the code using an OBD-II scanner and take the vehicle for a test drive to confirm that the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the system to ensure the P0964 code does not reappear after the test drive. | OBD-II Scanner |
