Doosan 185 Shuts off Under Load. Code Low Oil Pressure

by Chris
(Cherryvale, KS)

Compressor Shuts off under a load after running at full speed while sandblasting.


It flashes the code for low oil pressure.

Changed Oil and Filter.

Changed Air Filters.

I have replaced oil pressure sender.

I have installed oil pressure gauge and it carries 40-60 psi

I have replaced the main computer control box
I have ran a hot wire from battery to the hot side of the oil pressure sender.

This doesn't happen each use, but usually after it is warmed up.

Not a lot left but the harness.

I'd try removing the send wire and run a new one from the sender to the computer or whatever. (remove that end, too) Could be shorting to frame or another wire, or even going open.

Good luck, and let us know what happens, please.
