The P0773: Shift Solenoid E Electrical code refers to an electrical issue with shift solenoid “E.” This problem can disrupt the transmission’s ability to shift properly. It can be caused by faulty wiring, a malfunctioning solenoid, or poor connections.
P0773 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0773: Shift Solenoid E Electrical |
| Is it serious? | Yes, electrical problems with the solenoid can lead to improper shifting and drivability issues. |
| Possible causes | – Electrical issues with shift solenoid E – Faulty solenoid – Wiring problems |
| How to diagnose? | – Test solenoid E for electrical faults – Inspect wiring and connectors – Replace faulty solenoid if needed |
P0773 Meaning
The P0773 code indicates that the transmission control module (TCM) has detected an electrical fault in shift solenoid “E.” This solenoid controls the flow of transmission fluid, allowing for smooth gear shifting. Electrical problems can prevent it from functioning properly, leading to erratic or improper shifts.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional transmission-related codes that could give more insight into the issue. | OBD-II Scanner |
| Test Solenoid E for Electrical Faults | Use a multimeter or diagnostic tool to check the electrical continuity and functionality of solenoid E. Ensure it is receiving the proper voltage. | Multimeter, Diagnostic Scanner |
| Inspect Wiring and Connectors | Inspect the wiring and connectors leading to solenoid E for signs of damage, corrosion, or loose connections that could be causing electrical issues. | Flashlight, Multimeter, Safety Gloves |
| Check Transmission Fluid | Ensure that the transmission fluid level is correct and the fluid is clean, as low or contaminated fluid can affect solenoid performance. | Transmission Fluid Tester, Dipstick |
| Replace Faulty Solenoid | If solenoid E is found to be faulty, 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 wiring issues, clear the code using an OBD-II scanner and test drive the vehicle to confirm the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, rescan the vehicle to ensure the P0773 code has not returned. | OBD-II Scanner |
