Code 0192 Help

[ropinfool2]

Hello all, I had the CEL light up this weekend following maybe 5 seconds of rough idling. The only code showing is 0192 which I think is low rail pressure. The truck has been running fine since then. The CEL is still on, does this turn off by itself? And should I be worrying about the code? Thanks. JR

P0192 fuel pressure sensor voltage low. The sensor is on the fuel rail. Since the procedure is fairly detailed I will say to remove the connector, clean it up and seeif the code comes back. The light will go off 5 key cycles after the code is no longer active but the code will stay in the computer till cleared.

P0192 code, Does this mean the MPROP or FAC is bad? Or could it be a lift pump or injector pump?

It's the rail pressure sensor, wiring and ECM.
