Understanding and Fixing Doosan Fault Code VPV001-05 The VPV001-05 fault code is a specific diagnostic indicator commonly found on Doosan excavators (such as the DX180LC and DX300-5 series). It signals that the current for the Pump P1 (A) solenoid is below normal. Essentially, the machine's electronic control system has detected an electrical problem with the primary hydraulic pump's control circuit. What Does Code VPV001-05 Mean?
If you're dealing with a Doosan machine showing the fault code "VPv00105", I recommend reaching out directly to Doosan's customer support or a certified Doosan service provider for the most accurate and detailed information. doosan fault code vpv00105 new
VPV00105 indicates a Hydraulic Pump Pressure Sensor (Primary) – Voltage Out of Range High. The Engine Control Unit (ECU) or Pump Control Unit has detected that the voltage signal from the main hydraulic pump pressure sensor is above 4.9V (or 5.0V reference) for a calibrated period.

If you’ve replaced the sensor, inspected the harness, and updated the software, but VPV00105 returns within 10 operating hours, you may face a failing VCU. This is still rare on “new” machines but documented on 2022–2023 DX-5 series with VCU P/N 500714-00381. Doosan dealers can perform a “VCU output load test” to confirm.

Identify the Code: Make sure you have the correct code. Sometimes, codes can be similar or there might be a typo.
Based on the diagnostic findings, the repair path is usually one of the following:
