ECU 001347.07 – Fuel Rail Pressure Control Error / Control Valve 1 Fuel Pressure Deviation. John Deere System Advisory.
ECU 001347.07 (ECU 1347.07)
Code: 001347.07
Shortcode: 1347.07
Description:
Error code ECU 001347.07 is triggered when the ECU detects that the fuel rail pressure deviates by 5 MPa (50 bar; 725 psi) above or below the expected pressure. This deviation indicates a problem with the fuel pressure regulation at control valve 1.
Reaction:
The ECU may adjust engine parameters or limit performance to compensate for the fuel pressure deviation and prevent potential damage.
Recommendations:
- Inspect Fuel Pressure Control Valve: Check the fuel pressure control valve 1 for signs of malfunction. Ensure it is securely connected and functioning correctly.
- Verify Wiring and Connections: Examine the wiring and connectors related to the fuel pressure control valve 1 for any signs of damage, corrosion, or loose connections.
- Test Fuel Pressure: Use diagnostic tools to measure the fuel rail pressure and verify its accuracy. Compare the readings to the expected values and identify any significant deviations.
- Calibrate or Replace Faulty Sensor: If the pressure sensor is found to be inaccurate, calibrate it or replace it with a new one to ensure accurate pressure readings.
- Check for Mechanical Issues: Inspect the fuel system for any mechanical issues such as blockages, leaks, or faulty components that could affect fuel pressure regulation.
- Repair or Replace Faulty Components: Address any identified issues by repairing or replacing faulty wiring, connectors, sensors, or mechanical components.
- Reset ECU and Verify Operation: After addressing the fuel pressure deviation issue, reset the ECU to clear the error code and perform tests to ensure the fuel pressure control valve operates correctly and no further errors are detected.
Note:
Accurate fuel pressure regulation is crucial for optimal engine performance and fuel efficiency. Regular inspection and maintenance of the fuel pressure control system can help prevent deviation issues and maintain reliable engine operation.
