Most often, this fault is not with the hydraulic pump itself, but with its electrical control system. The most common causes include:
: Start with the basics. Verify that your engine coolant and hydraulic fluid levels are within the recommended range. Inspect the Wiring Harness
Apply dielectric grease to sensor connectors to prevent corrosion. doosan fault code vpv00105 new
: While primarily an electrical code, ensure hydraulic fluid levels are correct to prevent secondary pressure sensor errors. Resetting the Code
Check for signs of physical tearing, pinch points along the harness, or thick oil buildup around the connectors. Step 2: Test the Connector Connections Most often, this fault is not with the
Turn the ignition on for 30 seconds, then off for 30 seconds. Repeat this three times to allow the V-ECU to re-scan the circuit.
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. Inspect the Wiring Harness Apply dielectric grease to
Once any electrical issues have been repaired or any component has been replaced, you must reset the system.
