Technical Service Bulletin: Doosan Fault Code VPV00105

• You have replaced the sensor and repaired the harness, but the code returns instantly.
• You measure 5V reference present but 0V output, yet a new sensor does not fix it (likely a failed ECU pin).
• The machine has internal hydraulic contamination (metal shavings in the oil), which may have destroyed the sensor tip.

Doosan Dealer or Support

: For specific and detailed information, contacting a Doosan dealer or the company's customer support is advisable. They can provide accurate explanations and recommended actions for resolving the issue.

The sensor operates on a 5V reference line from the ECU. If the ECU’s ground is poor (often due to a loose battery ground or corroded chassis ground), the reference voltage floats, causing incorrect sensor readings. doosan fault code vpv00105 new

4. Common Fixes for New Pump Installation

Why this works:

The ECU has learned a "bad" sensor curve. Even after replacing the sensor, it uses the old adaptation values, triggering VPV00105 within 1 hour. This reset forces a fresh learn cycle. Technical Service Bulletin: Doosan Fault Code VPV00105

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. You have replaced the sensor and repaired the
