I have a D155AX-5 komatsu dozer, it has E01 error on the LCD. The machine works good but the only error I found when using the second switch from the right is: DH22KA DH21KB Any help?

    main hyd pump pressure sensor / wiring issue.

    you mean it could be wiring problem or hyd pump pressure sensor defected? There is a sensor on the MCV close to the main inlet from pump. This should be the hyd pressure sensor sensor having 3 wires connector no?
