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

The control module has detected an electrical fault (such as a short to ground, open circuit, or abnormal resistance) in the drive circuit that controls the fuel pressure control valve (Suction Control Valve) on the high-pressure fuel pump. This prevents the engine from properly regulating fuel rail pressure, often resulting in an engine derate or a no-start condition.

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.
