The type or make of engine doesn't matter much. The type of truck does. EX Freightliner, Kenworth Ect.

Ask a dealer if one sending unit energizes both.
I'd start with sending unit and associated wiring.

2001 peterbilt 378 thank you I will try that

Weird if they both went bad at same time.
Do you have a working air drier ?
Ever service it ?
If either answer is no, drain your air tanks. Daily until at least one answer is yes.
