Doosan Fault Code Vpv00105 New [new]

Before breaking out a digital multimeter, check the low-hanging fruit. Shut down the machine, let it cool completely, and check the expansion tank.

The pump may not respond correctly to operator commands.

After fixing the issue (e.g., replacing the sensor or repairing wires), you may need to clear the active fault code using a Doosan diagnostic tool or by cycling the power properly to ensure the ECU recognizes the repair.

: Look for any signs of damage, fraying, or shorting along the harness from the pump to the main controller. Check Hydraulic Fluid Before breaking out a digital multimeter, check the

Unplug the electrical connector leading directly to the P1 solenoid.

Ensure the engine coolant level is at the recommended, safe level. Low coolant can lead to rapid overheating, triggering the sensor to report abnormal temperatures. 2. Inspect Sensor Wiring Harness Locate the engine coolant temperature sensor. After fixing the issue (e

: The solenoid on the pump itself may have an internal failure. Blown Fuse or Relay

If VPV00105 appears on your newer Doosan machine, do not immediately replace the VCU. Follow this technician-verified workflow.

The Deutsch or AMP connectors used on Doosan pumps are water-resistant, but not waterproof. Dirt, green corrosion (verdigris), or a bent pin can create high resistance, triggering the "voltage high" alarm.

: Once repaired, start the engine and let it reach operating temperature. Use the Doosan monitoring panel or a diagnostic scan tool to clear the inactive fault code history. Verify that the dashboard coolant temperature gauge reads accurately and the machine exits limp mode.
