The pump may not respond correctly to operator commands.
To protect the engine block and cylinder head from catastrophic thermal failure, the Doosan ECM deploys specific failsafe parameters upon registering an invalid ECT sensor reading. Technicians should look out for the following system indicators:
: Moisture, debris, and engine degreasers penetrate weather seals, building high electrical resistance across the plug pins. doosan fault code vpv00105 new
Doosan fault codes are typically made up of letters and numbers that correspond to specific systems or components of the machine and the nature of the fault. Here's a general breakdown:
The on Doosan excavators, such as the DX180LC and other modern "new" generation models, is typically associated with the engine coolant temperature sensor .

The code "VPV00105" is not listed in older, publicly available Doosan fault code lists. However, using the logic of Doosan's system, we can make a highly educated deduction:
Use a multimeter to check if the sensor is providing the correct voltage (usually 5V reference) and signal range.
: Use an infrared thermometer to verify actual block temperature. As the engine gets hot, the resistance should drop smoothly down to 200–300 ohms. An infinite reading ( ∞infinity Can’t copy the link right now
on your Doosan excavator's display, you aren't alone. This specific error often appears on DX series machines, such as the
Use a multimeter to check the resistance of the P1 pump solenoid. If the resistance is outside the manufacturer's specified range (indicating an open or shorted coil), the solenoid must be replaced.
If the code persists after cleaning the filters and checking the wiring, the issue likely lies with a failing or a fault within the Electronic Control Module itself.
: Rubbing, pinching, or heat exposure can break or fray the wiring jacket between the main controller and the hydraulic pump tower.
