2005 Ford V-10 E-450 Chassis.  I routinely get the Code PO 191 when acceleration to highway speed after a brief engine turn-off.  The code indicates "Fuel  Pressure Sensor Circuit Performance".  The engine has no driveability issues.  All service items are current.  Scanning guage clears the code.

Welcome to FMCA !

 

Possible causes:

 

-High fuel pressure
- Low fuel pressure
- Damaged FRP sensor
- Excessive resistance in the circuit
- Low or no fuel
- Wiring harness connector of the fuel pressure sensor
- Fuel Rail Pressure Sensor
- Vacuum leaks
- Fuel
