Use proper, clean coolant to prevent sensor fouling.

The internal coil of the specific hydraulic solenoid may be failing. If the coil overheats or suffers an internal short, its resistance changes, prompting the V-ECU to trip the VPV00105 code. 4. Controller Voltage Drops

For the most accurate and up-to-date information on Doosan fault codes, including "VPv00105," it's essential to stay in touch with Doosan's customer service or consult their official website and documentation regularly. Manufacturers often update their databases and documentation as new issues are identified and resolved.

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.

In plain English: The computer that controls your hydraulic pump is not getting a clear signal about how much pressure the pump is making. It sees "New" (active/unresolved) fault because the reading is outside the expected range.

After executing the repair, start the machine and let it reach standard operating temperature. Navigate to the on-board service monitor menu to confirm that the fault code status shifts from "Active" to "Stored" or "Passive," then clear the code completely.

: Use a multimeter to check the continuity of the wiring between the EPOS (Electronic Power Optimizing System) controller and the pump solenoid.

Low hydraulic fluid or coolant levels can sometimes trigger sensor errors. Inspect Electrical Connections:

If you’re a fleet manager, document every occurrence of VPV00105. Doosan’s engineering team has acknowledged that a batch of pressure sensors from mid-2022 had a higher-than-acceptable voltage drift rate. Your data could qualify for a warranty extension.

If the code persists after these steps, you may need to use a digital multimeter to check for specific voltage drops at the ECU pins. exact location of the P/V valve on your specific Doosan model? Doosan Fault Codes List PDF - Scribd
