Doosan - Fault Code Vpv001-05

If the valve coil tests healthy, you must check the wiring between the valve and the EPOS control module.

Easy to Medium.

/ "OL" (open circuit), the solenoid coil is dead and the valve assembly must be replaced. Step 3: Circuit Harness Voltage & Continuity Verification doosan fault code vpv001-05

Locate the ECT sensor, typically positioned near the thermostat housing on the upper engine block.

Touch the multimeter probes directly to the two male terminal pins inside the . If the valve coil tests healthy, you must

Disconnect and clean the electrical connector with an electronic contact cleaner to remove corrosion. Solenoid Resistance Test

Anyone know the cure for this on a Doosan? Thanks - Facebook Step 3: Circuit Harness Voltage & Continuity Verification

An "OL" or infinite reading indicates an internal open circuit, requiring solenoid replacement. Controller Output Verification Check for voltage output from the

If the controller is sending a signal but it isn't reaching the solenoid, the break is in the wiring harness. Fluid & Temperature Secondary Checks

Several factors can contribute to the generation of fault code VPV001-05. Some of the possible causes include:
