thank you very much i've checked all of the harness connections in the fuel system and cleared it and lasted 15 mins with no error code, unit is not a dual fuel and has no provisions anywhere for gas

Fuel specification determination signal error..could be bad connector, bad fuel changeover switch, harness defect or even engine controller

The code is for a fuel change over switch issue or harness issue. I am assuming that this is a dual fuel truck. I would check the switch and all connections first.
