The Doosan fault code indicates that the current for the Pump P/V (A) is below normal . This error typically pertains to the primary hydraulic pump (Pump P1) and its proportional pressure-reducing valve on Doosan excavators, such as the DX140W-5 or DX180LC. When this code triggers, the machine’s electronic control unit (ECU) has detected that the electrical signal sent to the pump's solenoid is lower than the expected operating range. Potential Causes

By following the structured troubleshooting guide above—prioritizing safety, measuring actual incoming voltage, and performing insulation resistance tests—you can quickly isolate the root cause. Addressing the underlying issue promptly will save thousands of dollars in unplanned downtime and prevent catastrophic damage to your Doosan CNC’s power electronics. The Doosan fault code indicates that the current
If you've checked the connections and the resistance is off, you likely need a replacement Potential Causes Notes and assumptions Elias stared
: Some mechanics have previously associated this code with the engine coolant temperature sensor, but diagnostic software typically maps "VPV" codes directly to Pump Proportional Valve JustAnswer specific resistance values
