Find the pilot pressure sensor (VPV) on your DX series machine (commonly near the pilot valve manifold).
Doosan Fault Code VPV00105 (New) indicates that the ECU has detected an abnormal voltage level from the main variable displacement pump pressure sensor. The signal received is either consistently higher than 4.8 volts (short to high) or 0 volts (short to ground), or the sensor circuit is open.
: Water or coolant intrusion into the sensor connector plugs rots the copper connections. doosan fault code vpv00105 new
This involves locating the P1 pump's proportional solenoid and checking its electrical health.
If both sensor and wiring are tested to be in good condition, the main controller (MCU) might not be interpreting the signal correctly.

Switch the machine’s ignition to the "ON" position without starting the engine. Check for proper voltage (usually 5V or 12V reference) coming from the wiring harness side of the plug. Ensure the machine's main chassis grounds are clean and tight. How to Clear the Code
To resolve this issue, follow these steps in order to isolate the fault. 1. Initial Inspection (Visual) : Water or coolant intrusion into the sensor
Result interpretation: If the 5V signal is missing, the problem lies in a broken wire between the sensor plug and the main ECM harness, or a blown system fuse. 3. Sensor Resistance (Continuity) Testing Set the digital multimeter to the Ohms ( Ωcap omega ) setting.
Potential causes include:
If you operate heavy machinery—specifically Doosan excavators, wheel loaders, or articulated dump trucks—you’ve likely encountered the cryptic alphanumeric code on your display panel. Recently, searches for “Doosan fault code VPV00105 new” have spiked. This guide explains what this code means, why “new” appears in troubleshooting forums, and the step-by-step procedure to diagnose and resolve it.
