Hello everyone! I’m having issues with my excavator 2003 kobelco SK210lc 6 I’m getting “B-11 P1 NEGATIVE PRESSURE SENSOR IS ABNORMAL” code. Please help I don't know what to do. I already found the sensor it’s on the top of the main pump. The machine works fine, but with acc on it beeps. Thank you for you comments
Remove both p1 and p2 sensors and swap them over if the screen changes to p2 then your sensor is faulty if it continues to flash p1 check the wiring to p1 sensor
