Code Vpv00105 New [hot] — Doosan Fault

It often appears intermittently under heavy load, then becomes permanent.

The Deutsch or AMP connectors used on Doosan pumps are water-resistant, but not waterproof. Dirt, green corrosion (verdigris), or a bent pin can create high resistance, triggering the "voltage high" alarm.

The sensor itself has failed and is sending incorrect data to the ECU. doosan fault code vpv00105 new

Switch the excavator's battery disconnect on and turn the ignition key to the position (do not start the engine).

In the world of heavy construction and material handling, engines and hydraulic systems are renowned for their reliability. However, like any sophisticated piece of machinery, they rely on a complex network of sensors and Electronic Control Units (ECUs). When a problem arises, the machine’s diagnostics system generates a fault code to guide your repair. It often appears intermittently under heavy load, then

A DPF is a ceramic filter, typically made of cordierite or silicon carbide, installed in the exhaust system of a diesel engine. Its job is to capture and store exhaust soot (particulate matter) to reduce emissions and comply with Tier 4 Final/Stage V environmental regulations. Over time, this captured soot will build up. If it isn't removed, the DPF will clog, causing severe backpressure on the engine, which leads to a loss of power, increased fuel consumption, and eventual engine damage.

: Internal component failure inside the sensor can break the circuit entirely, preventing it from varying its resistance based on temperature. The sensor itself has failed and is sending

: Ensure that all connections are secure, and there are no obvious signs of damage or wear on components that could be related to the fault.

Locate the coolant temperature sensor on the top thermostat housing or side engine block.

: Follow the wiring harness back from the sensor looking for signs of rubbing, pinching, or heat damage.
