The P0969: Pressure Control Solenoid ‘C’ Control Circuit Range/Performance refers to an issue where the pressure control solenoid ‘C’ circuit is operating outside its expected range or performance parameters. This can result in improper transmission pressure regulation, leading to shifting issues and overall poor transmission performance.
P0969 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0969: Pressure Control Solenoid ‘C’ Control Circuit Range/Performance |
| Is it serious? | Yes, range or performance issues can lead to poor transmission pressure regulation, causing shifting problems. |
| Possible causes | – Range or performance issues with the pressure control solenoid ‘C’ circuit – Faulty pressure control solenoid ‘C’ – Wiring or connector issues |
| How to diagnose? | – Test the pressure control solenoid ‘C’ circuit for range and performance – Inspect wiring and connectors – Replace faulty components if needed |
P0969 Meaning
The P0969: Pressure Control Solenoid ‘C’ Control Circuit Range/Performance code indicates that the pressure control solenoid ‘C’ is not functioning within its expected range. The solenoid helps regulate hydraulic pressure in the transmission, and any deviation from its operating range can lead to transmission issues, including rough shifting or 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 may provide more context about the range or performance issue. | OBD-II Scanner |
| Test for Range and Performance | Use a multimeter or diagnostic tool to test the pressure control solenoid ‘C’ circuit for range and performance, ensuring it operates within the manufacturer’s specifications. | Multimeter, Diagnostic Tool |
| Inspect Wiring and Connectors | Inspect the wiring and connectors for signs of damage, corrosion, or loose connections that could be affecting the solenoid’s performance. | Flashlight, Multimeter |
| Test the Solenoid | Test the pressure control solenoid ‘C’ for proper operation. Replace the solenoid if it is not functioning within its specified range. | Diagnostic Tool, Replacement Solenoid |
| Clear the Code and Test Drive | After making repairs, clear the code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the system to ensure the P0969 code does not reappear after the test drive. | OBD-II Scanner |
