Hyster S70FT:
Fault 100-4

I have 2 Hyster S70FTs, both have a fault code of 100-4. The one runs fine but the code stays on. The other one will not start. Can anyone help with this. Our local Hyster guy was down and told us it was the oil pressure sender. We replaced the sender with no change. Thanks for any help

When you check the oil pressure reading the dash assembly under diagnostics, does it show a numeric value or question marks?
