ECU 000157.18 – Moderately Low Fuel Rail Pressure Detected. John Deere System Advisory.

ECU 000157.18 (ECU 157.18)

Code: 000157.18

Shortcode: 157.18


ECU 000157.18 is triggered when the fuel rail pressure is slightly below the desired level, indicating a potential issue with fuel delivery or pressure regulation. This condition might be caused by a partially clogged fuel filter, issues with the fuel pump, or a faulty pressure regulator.


The engine may exhibit reduced power output and efficiency as the ECU attempts to compensate for the lower-than-expected fuel pressure.


  • Inspect Fuel Pump and Pressure Regulator: Evaluate the operation of the fuel pump and pressure regulator to ensure they are functioning properly.
  • Check Fuel Filters and Lines: Inspect fuel filters and lines for any blockages or leaks that might be contributing to pressure loss.
  • Perform Fuel System Diagnostics: Use diagnostic equipment to precisely measure fuel pressure and identify any discrepancies from normal levels.
  • Repair or Replace Faulty Components: Address any issues found during the diagnostic checks by repairing or replacing faulty components as necessary.
  • Reset ECU and Clear Error Codes: After making the necessary adjustments, reset the ECU to ensure it accurately monitors and regulates fuel pressure.


Routine maintenance of the fuel system is crucial to prevent pressure-related issues and ensure optimal engine performance.
