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
