The controller (V-ECU) detects that the electrical current flowing to the valve is lower than the expected operating range.
If you’re a fleet manager, document every occurrence of VPV00105. Doosan’s engineering team has acknowledged that a batch of pressure sensors from mid-2022 had a higher-than-acceptable voltage drift rate. Your data could qualify for a warranty extension.
The VPV code series typically relates to the (also known as the EPPR valve) which regulates hydraulic pump output based on signals from the EPOS controller. The "-05" suffix indicates that the electrical current being sent to the valve is lower than the expected operating range, often pointing to a physical break in the electrical circuit or a disconnected plug. 3. Troubleshooting & Diagnostic Steps Follow these steps to isolate the cause: Step 1: Visual Inspection Locate the P1 (main) pump and its proportional valves. doosan fault code vpv00105 new
: Loose, corroded, or damaged wiring connectors at the P1 pump solenoid. Faulty Pump Solenoid
Use a can of electrical contact cleaner to clear out any grease or dirt. 3. Test Voltage and Ground Sides The controller (V-ECU) detects that the electrical current
Based on field service reports from 2021–2025, here are the top six triggers for VPV00105:
A DPF is a ceramic filter, typically made of cordierite or silicon carbide, installed in the exhaust system of a diesel engine. Its job is to capture and store exhaust soot (particulate matter) to reduce emissions and comply with Tier 4 Final/Stage V environmental regulations. Over time, this captured soot will build up. If it isn't removed, the DPF will clog, causing severe backpressure on the engine, which leads to a loss of power, increased fuel consumption, and eventual engine damage.

: If the issue persists and you're unable to resolve it, consulting a professional technician authorized by Doosan is the best course of action. They will have the necessary expertise and equipment to diagnose and fix the problem.
VPV00105 System: Hydraulic Main Pump (Variable Displacement) Equipment Affected: Doosan Excavators (e.g., DX140, DX180, DX225, DX300 series) and Wheel Loaders using electronic pump control. Symptom: New pump installed; code appears immediately or shortly after startup.
A predictive diagnostic algorithm that runs in the background during machine startup and operation, detecting the precursors to VPV00105 before the actual fault code is thrown.
