Doosan Fault Code Vpv00105 New Verified

When this code is active, the machine may enter a "limp mode" or experience severely reduced hydraulic performance, as the ECU cannot properly regulate the P1 pump's output.

| Symptom / FMI | Likely Cause | Solution | |---------------|--------------|----------| | FMI 5 (open circuit) | Broken wire, corroded connector pin, failed solenoid coil | Inspect harness for breaks; measure coil resistance; replace solenoid if out of spec | | FMI 6 (grounded circuit) | Wire shorted to chassis, internal component short | Isolate circuit; check for melted wires; replace shorted sensor/valve | | FMI 2 (intermittent signal) | Loose connector, chafed wire that intermittently touches ground | Wiggle harness while monitoring data; repair chafed area; tighten connector | | FMI 3 / 4 (voltage high/low) | Bad sensor, faulty controller output, or wiring short to power/ground | Compare sensor supply voltage to spec; replace sensor; check controller ground | | FMI 0 / 1 (pressure out of range) | Clogged hydraulic filter, stuck valve, or damaged pump | Replace filter; clean or replace valve; test pump pressure with gauge |

The controller (V-ECU) detects that the electrical current flowing to the valve is lower than the expected operating range.
