P2723 Pressure Control Solenoid "E" Performance/Stuck Off

The OBD2 code P2723 indicates that the Pressure Control Solenoid "E" is either not performing correctly or is stuck in the "off" position, which can affect transmission fluid pressure and overall transmission performance

Definition

The OBD2 code P2723 indicates that the Pressure Control Solenoid "E" is either not performing correctly or is stuck in the "off" position, which can affect transmission fluid pressure and overall transmission performance

Common causes

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

Common misdiagnoses

  • Faulty transmission control module (TCM)
  • Incorrectly diagnosed transmission fluid issues
  • Misidentified wiring or connector problems
  • Faulty pressure control solenoid "E"
  • Transmission valve body issues
  • Misdiagnosed internal transmission problems
  • Incorrectly assumed engine performance issues
  • Faulty or miscalibrated throttle position sensor (TPS)

Troubleshooting steps

  1. 1. 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

  2. 2. Inspect Transmission Fluid

  3. 3. Check the transmission fluid level and condition. Low or dirty fluid can affect solenoid performance

  4. 4. If the fluid is dark, burnt, or has a burnt smell, consider changing it

  5. 5. Visual Inspection

  6. 6. Inspect the wiring and connectors related to the pressure control solenoid "E" for any signs of damage, corrosion, or loose connections

  7. 7. Look for any signs of leaks around the transmission

  8. 8. Test the Pressure Control Solenoid "E"

  9. 9. Use a multimeter to test the resistance of the solenoid. Compare the readings to the specifications in the vehicle's service manual

  10. 10. If the solenoid is not within specifications, it may need to be replaced

  11. 11. Check for Mechanical Issues

  12. 12. Inspect the transmission for any mechanical issues that could affect solenoid operation, such as sticking valves or internal wear

  13. 13. A transmission fluid pressure test may be necessary to ensure the system is functioning correctly

  14. 14. Scan for Transmission Data

  15. 15. Use a scan tool to monitor live data while the vehicle is running. Look for any irregularities in the transmission fluid pressure readings or solenoid activation

  16. 16. Check the Transmission Control Module (TCM)

  17. 17. Ensure that the TCM is functioning properly. A malfunctioning TCM can cause solenoid issues

  18. 18. If necessary, reprogram or replace the TCM according to manufacturer specifications

  19. 19. Clear Codes and Test Drive

  20. 20. After performing any repairs or replacements, clear the trouble codes and take the vehicle for a test drive to see if the code returns

  21. 21. Consult a Professional

  22. 22. If the issue persists after performing these steps, it may be necessary to consult a professional mechanic or transmission specialist for further diagnosis. By following these steps, you can systematically identify and address the underlying issues related to the P2723 code
