John Deere 613.31 – ECU: Voltage Issue For High Pressure Fuel Pump Solenoid

The Engine Control Unit (ECU) has detected an electrical voltage issue within the driver circuit of the fuel pressure control valve (solenoid). This valve regulates the amount of fuel entering the high-pressure pump to supply the common rail. A voltage anomaly prevents the solenoid from actuating correctly, resulting in excessive or insufficient fuel pressure, which can lead to significant performance degradation or engine shutdown.

1. 1

   Inspect the harness connector at the high-pressure fuel pump solenoid (Suction Control Valve) for looseness, corrosion, or pushed-out pins

2. 2

   Test the wiring harness between the ECU and the fuel pump solenoid using a multimeter to check for continuity, high resistance, or a short to ground

3. 3

   Ensure the battery is fully charged and the alternator is providing the correct voltage, as low system voltage can trigger false solenoid drive faults

4. 4

   Measure the internal resistance of the Suction Control Valve coil to determine if it is out of specification (shorted internally or open)

1. 1

   Disconnect Power

   Disconnect the negative battery cable before servicing the fuel system electronics.

2. 2

   Repair Wiring

   If the diagnostic checks revealed a short or break in the harness, repair the damaged section of the wiring or replace the pigtail connector.

3. 3

   Replace the Solenoid

   If the wiring is intact but the valve failed the resistance test, clean the area around the high-pressure fuel pump to prevent contamination. Remove the mounting bolts securing the Suction Control Valve to the pump and extract the valve. Lubricate the O-rings on the new valve with clean diesel fuel and install it, torquing the bolts to OEM specifications.

4. 4

   Reassemble and Prime

   Reconnect the electrical harness and battery. Prime the fuel system to remove any air introduced during the repair.

5. 5

   Reset ECU and Test

   Clear the 000613.31 fault code from the ECU using a diagnostic tool. Run the machine under various operating conditions to verify the fuel pressure tracks the commanded pressure and the code does not return.
