Code Vpv00105 New __exclusive__ — Doosan Fault

VPV001-05

The Doosan fault code indicates that the PUMP P/V (A) current is below normal . This is typically an electrical error suggesting an open circuit in the proportional pressure-reducing valve of the hydraulic pump. Error Breakdown

  • Turn off the machine and disconnect the negative battery terminal.
  • Use Ohms mode on your DMM.
  • Check resistance from the sensor Signal pin to chassis ground. It should be Open Line (OL).
  • If you see 0 Ohms: The wire is pinched to the frame. Repair the harness.

When the machine's control unit detects that the electrical current sent to the P1 pump solenoid is lower than the expected operating range, it triggers this "active" fault. An active code means the problem is currently occurring and may affect machine performance or safety. Potential Causes Electrical Wiring Issues doosan fault code vpv00105 new

  • Stuck or mechanically failed VPV (valve jammed open/closed)
  • Faulty pressure/vacuum sensor feeding the controller incorrect readings
  • Damaged wiring or loose/ corroded connector at the valve or sensor
  • Low system vacuum/pressure due to leaks or failing pump
  • Control module/ECU software glitch or calibration issue
  • Recent service, replacement, or new part that’s incompatible (the “new” in your query suggests a replaced component)

If you’ve replaced the sensor, inspected the harness, and updated the software, but VPV00105 returns within 10 operating hours, you may face a . 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.
