The P0764: Shift Solenoid C Intermittent refers to an issue where the operation of shift solenoid “C” is inconsistent, leading to irregular transmission behavior. This may be caused by a faulty solenoid, wiring problems, or loose electrical connections.
P0764 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0764: Shift Solenoid C Intermittent |
| Is it serious? | Yes, intermittent faults can cause unpredictable gear shifts and drivability issues. |
| Possible causes | – Intermittent issues with shift solenoid C – Faulty solenoid – Wiring or connection issues |
| How to diagnose? | – Test solenoid C for intermittent faults – Inspect wiring and connectors – Replace faulty solenoid if necessary |
P0764 Meaning
The P0764 code indicates that shift solenoid “C” is experiencing intermittent operation, which can cause erratic gear shifting, delayed engagement, or transmission slippage. Intermittent issues are often caused by faulty wiring, loose connections, or a failing solenoid.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to detect additional transmission-related codes that may help pinpoint the issue. | OBD-II Scanner |
| Test Solenoid C for Intermittent Faults | Use a multimeter or diagnostic scanner to test solenoid C for electrical continuity and performance under different conditions. Look for irregular or inconsistent operation. | Multimeter, Diagnostic Scanner |
| Inspect Wiring and Connectors | Inspect the wiring and connectors leading to solenoid C for signs of wear, loose connections, or corrosion that could cause intermittent performance. Repair or replace as necessary. | Flashlight, Multimeter, Safety Gloves |
| Check Transmission Fluid | Verify that the transmission fluid is at the correct level and clean, as low or dirty fluid can affect solenoid performance. Adjust fluid level if necessary. | Transmission Fluid Tester, Dipstick |
| Replace Faulty Solenoid | If solenoid C is malfunctioning intermittently, replace it with a new solenoid according to manufacturer specifications. | Replacement Parts, Wrenches, Screwdrivers |
| Clear the Code and Test Drive | After replacing the solenoid or addressing any wiring issues, clear the code using an OBD-II scanner and test drive the vehicle to verify that the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, rescan the vehicle to ensure the P0764 code has not returned. | OBD-II Scanner |
