The P0771: Shift Solenoid E Performance or Stuck Off refers to a problem where shift solenoid “E” is either not performing correctly or is stuck in the “off” position, preventing proper gear shifting. This issue may result from a faulty solenoid, wiring problems, or connector issues.
P0771 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0771: Shift Solenoid E Performance or Stuck Off |
| Is it serious? | Yes, poor performance or a stuck solenoid can cause drivability issues and affect gear shifting. |
| Possible causes | – Performance issues or solenoid E stuck off – Faulty solenoid – Wiring issues |
| How to diagnose? | – Test solenoid E for performance issues or stuck-off condition – Inspect wiring and connectors – Replace faulty solenoid if needed |
P0771 Meaning
The P0771 code indicates that shift solenoid “E” is either not functioning properly or is stuck in the “off” position. Shift solenoids regulate the flow of transmission fluid, allowing for smooth gear shifts. If solenoid “E” is not performing as expected, it can cause improper or delayed gear shifting, impacting the vehicle’s performance.
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 may provide more context for diagnosing the issue. | OBD-II Scanner |
| Test Solenoid E for Stuck-Off Condition | Use a multimeter or diagnostic scanner to test solenoid E for electrical continuity and proper operation. Verify if it is stuck in the “off” position. | Multimeter, Diagnostic Scanner |
| Inspect Wiring and Connectors | Inspect the wiring and connectors leading to solenoid E for signs of wear, damage, or loose connections that could cause the solenoid to remain off. | Flashlight, Multimeter, Safety Gloves |
| Check Transmission Fluid | Ensure the transmission fluid level is correct and that the fluid is clean, as low or contaminated fluid can affect solenoid performance. | Transmission Fluid Tester, Dipstick |
| Replace Faulty Solenoid | If solenoid E is malfunctioning or stuck off, 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 verify the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, rescan the vehicle to ensure the P0771 code has not returned. | OBD-II Scanner |
