Check for chafing, broken wires, or rodent damage to the harness leading to the sensor. 3. Examine the Sensor Connector
Test for continuity between the valve connector and the corresponding pins on the EPOS/ECU controller .
The alphanumeric structure of modern Doosan diagnostic trouble codes (DTCs) points directly to a system, a component, and the nature of the failure.
You may notice immediate changes in your Doosan equipment’s operation when this code surfaces: doosan fault code vpv00105 new
Compare your reading with Doosan's standard factory specifications (typically between , depending on the exact system voltage). Open Circuit ( ∞infinity
For more detailed technical breakdowns, you can often find model-specific manuals on platforms like or seek advice from certified heavy equipment mechanics on JustAnswer Doosan Forklifts Error Codes - CLaME
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 Check for chafing, broken wires, or rodent damage
The excavator's computer may limit pump displacement, leading to sluggish arm, boom, or bucket operations.
: Doosan's official website or their customer support can be a valuable resource. They often have databases of fault codes and troubleshooting guides.
Using a multimeter, test for the correct voltage signal (sensor input high/low). exact location of the P/V valve on your
Apply dielectric grease to sensor connectors to prevent corrosion.
An indicates an open coil that must be replaced. Step 3: Check Wiring Continuity and Voltage
The points directly to an open circuit or low current issue within the Engine Coolant Temperature (ECT) sensor system . Commonly triggered on heavy machinery like the Doosan DX180LC Excavator , this "new" or active error code flags that the Engine Control Module (ECM) is completely losing communication with the sensor or reading data outside standard physical ranges.
Check for chaffing points around the engine bay.
Use an independent infrared thermometer to read the temperature of the engine block near the thermostat housing. Compare this directly to what your machine display shows. If the machine display is frozen at a default value while the engine is physically warm, the ECM is running on backup logic because of the active fault. Resolution Matrix Diagnostic Finding Root Cause Corrective Action Air pockets around sensor Top off coolant and bleed the air system. Infinite resistance (OL) on sensor Broken internal sensor circuit Replace the Engine Coolant Temperature Sensor. Green/white build-up in plug Moisture contamination Clean with contact cleaner and apply dielectric grease. Cut or chafed wires Harness abrasion against metal Splice damaged wires or replace the harness subsection. How to Clear the Code
