: Use a multimeter to check the resistance of the P1 solenoid. Compare the reading to the specifications in your specific Doosan service manual. Monitor Voltage
In some newer models with certain software versions, the "VPV00105" code or the "2107—DPF regeneration" message is the new standard way the system communicates that an has been automatically triggered and is currently running. In this case, it should not be treated as an error.
The solenoid valve on the P1 pump (Primary Pump A) has failed internally. doosan fault code vpv00105 new
The pump may not respond correctly to operator commands.
The Master Malfunction Indicator Lamp (MIL) illuminates alongside the specific alphanumeric readout on the digital control monitor. Step-by-Step Troubleshooting and Diagnostic Protocol
The "new" nature of this fault code frequently indicates that the issue is electrical rather than mechanical damage. Common causes include: Disclaimer: This article is for informational purposes
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.
: Ensure that operators and maintenance personnel are properly trained on the equipment and familiar with diagnostic procedures.
The VPV001-05 fault code on a Doosan excavator signifies a low current or open circuit in the P1 hydraulic pump solenoid. Troubleshooting steps include checking the electrical harness for damage, testing the solenoid for continuity, and ensuring proper hydraulic fluid levels.

This code indicates that the Engine Control Module (ECM) is detecting a signal voltage from the coolant temperature sensor that is outside the normal operating range, often pointing to an or short circuit within the sensor wiring harness. Common Symptoms Engine Derate: The machine may enter a reduced-power mode.
Now that you have the full context, here are the actionable steps to identify and resolve the VPV00105 fault code. Follow this troubleshooting guide sequentially.
According to technical documentation, fault code indicates a problem with the Engine Coolant Temperature (ECT) Sensor . Specifically, this code typically flags that the sensor or its associated wiring is sending an incorrect voltage signal—either too high or an open circuit—to the Engine Control Unit (ECU). Common Symptoms: Monitor displays VPV001-05. Engine check light / warning alarm. Potential for reduced engine power (derate mode). Engine may be running too hot or the system thinks it is.
