Hello, I'm new on here. I have an '05 Bobcat t190 with keyless start. Today while running the machine an error came up saying hydraulic oil temperature is too hot so we shut down the machine. Hydraulic oil was full. 30 minutes later we started up the machine and got codes 04-21, 47-22 and 08-22. That's high oil pressure, no coolant temp reading and zero hydro pressure. The machine runs fine and when we press the traction lock bypass button it drove on the trailer fine. Also the bics system will not turn on. It seams to me that all these sensors can't go down at the same time so I'm thinking it's electrical somewhere. Has anyone heard of this problem. What should I do to start repairing? Thank you for any help.
