P0772 – Shift Solenoid E Stuck On

The ODBII code P0772 indicates that the Shift Solenoid E is stuck in the “on” position, which can affect the transmission’s ability to shift gears properly.

The severity of ODBII code P0772 is moderate to severe.

Common Causes For: P0771 Shift Solenoid E Performance or Stuck Off

• Faulty shift solenoid E
• Wiring issues or damaged connectors
• Low transmission fluid level
• Contaminated transmission fluid
• Faulty transmission control module (TCM)
• Internal transmission problems
• Poor electrical connections
• Malfunctioning valve body

Common misdiagnosis for P0772 Shift Solenoid E Stuck On

• Transmission fluid issues
• Faulty transmission control module (TCM)
• Wiring or connector problems
• Other shift solenoid failures
• Valve body issues
• Torque converter problems
• Internal transmission damage

Common Troubleshooting Steps

The OBD-II code P0772 indicates that the transmission control module (TCM) has detected a problem with the Shift Solenoid E, specifically that it is stuck in the “on” position. This can lead to various transmission issues, including erratic shifting or slipping. Here are some common troubleshooting steps to diagnose and potentially resolve the issue:

• Check for Additional Codes: Use an OBD-II scanner to check for any other trouble codes that may be present. This can provide more context and help identify related issues.
• Inspect Transmission Fluid: **Fluid Level:** Check the transmission fluid level. Low fluid can cause shifting issues.
• **Fluid Condition:** Inspect the fluid for contamination, burning smell, or dark color. If the fluid is dirty or burnt, consider a transmission fluid change.
• Examine Wiring and Connectors: Inspect the wiring harness and connectors leading to the Shift Solenoid E for any signs of damage, corrosion, or loose connections. Repair or replace as necessary.
• Test the Shift Solenoid E: Use a multimeter to test the resistance of the Shift Solenoid E. Compare the readings to the manufacturer’s specifications. If the solenoid is out of spec, it may need to be replaced.
• Check for Mechanical Issues: Inspect the transmission for any mechanical issues that could affect the solenoid’s operation, such as sticking valves or internal wear.
• Clear Codes and Test Drive: After performing any repairs or adjustments, clear the trouble codes using the OBD-II scanner and take the vehicle for a test drive to see if the code returns.
• Inspect the Transmission Control Module (TCM): If the problem persists, the TCM itself may be faulty. Check for updates or recalls related to the TCM for your vehicle model.
• Consult a Professional: If you are unable to resolve the issue after these steps, it may be best to consult a professional mechanic or transmission specialist for further diagnosis and repair.Additional Considerations
• Vehicle-Specific Information:** Always refer to the vehicle’s service manual for specific diagnostic procedures and specifications.
• Safety Precautions:** Ensure the vehicle is safely supported and that you take necessary precautions when working on the transmission. By following these steps, you can systematically diagnose and address the issue related to the P0772 code.
