Doosan fault code indicates that the electrical current in the Pump Proportional Valve (P1/A) circuit is below normal or is experiencing an open circuit . This diagnostic trouble code (DTC) is common across various Doosan excavator models, such as the DX180LC , DX230LC , and DX300LC .
Locate the Variable Pump Valve on the main pump or control valve bank and check for loose or corroded connectors. Use a specialized cleaner from retailers like CRC Industries to clean any grime.
Moisture ingress or dirt in the electrical connectors can increase resistance or cause an open circuit.
Using a multimeter , measure the resistance across the solenoid terminals. A healthy solenoid typically reads between 3-8 ohms (check your specific model's manual for exact specs).
Check for continuity between the ECU and the valve connector to rule out internal wire breaks.
