The P0968: Pressure Control Solenoid ‘C’ Control Circuit/Open refers to an open circuit in the pressure control solenoid ‘C’. This issue can prevent the solenoid from regulating transmission fluid pressure properly, leading to transmission performance problems like improper shifting or slippage.
P0968 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0968: Pressure Control Solenoid ‘C’ Control Circuit/Open |
| Is it serious? | Yes, an open circuit can result in improper transmission pressure regulation and poor shifting performance. |
| Possible causes | – Open circuit in the pressure control solenoid ‘C’ – Faulty pressure control solenoid ‘C’ – Wiring or connector issues |
| How to diagnose? | – Check the circuit for continuity – Inspect wiring and connectors – Replace the pressure control solenoid ‘C’ if necessary |
P0968 Meaning
The P0968: Pressure Control Solenoid ‘C’ Control Circuit/Open code indicates that the pressure control solenoid ‘C’ circuit is open or disconnected, preventing it from operating correctly. This solenoid regulates hydraulic pressure in the transmission, and an open circuit can lead to poor transmission performance, including shifting issues and transmission slipping.
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 might provide further context about the open circuit issue. | OBD-II Scanner |
| Test for Circuit Continuity | Use a multimeter to check for continuity in the pressure control solenoid ‘C’ circuit. Ensure there is no open circuit or disconnection. | Multimeter |
| Inspect Wiring and Connectors | Inspect the wiring and connectors for signs of damage, corrosion, or loose connections in the pressure control solenoid ‘C’ circuit. | Flashlight, Multimeter |
| Test the Solenoid | Use a diagnostic tool to test the pressure control solenoid ‘C’ for proper functionality. Replace the solenoid if it is faulty or damaged. | 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 the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the system to ensure the P0968 code does not reappear after the test drive. | OBD-II Scanner |
