Hi, I have a kobelco ed150-1e. I keep getting the p2 propo valve code after machine warms the hydraulic system up. If I turn it off and let it cool then it goes away until oil is warm again. I tested the wires all the way to the controller and the have continuity. My diagnostic screen for p2 solenoid valve says that the comp. Is good but meas. Is only around 9. Any ideas?
Hi it probably faulty pump solenoid valve to check swap the wires between p1 and p2 solenoids. If p1 solenoid fault then appears its a faulty solenoid, if p2 stills appears then either wiring or controller is at fault.
