If you have already replaced the sensor, or if you can see which specific wiring harness (pilot manifold, main valve block) is causing the issue, let me know, and I can give you more targeted testing steps for the wiring. let me know
While primarily an electrical code, ensure hydraulic fluid levels are correct to prevent mechanical strain that might exacerbate system warnings. Operational Impact doosan fault code vpv00105 new
