The pressure in your fuel injection system is too high. You might need a new fuel pump or fuel regulator. Disconect the fuel line and check the pressure with a gauge {should be about 14 psi}. If it is its the regulator, if not the pump.

SOURCE: Fuel rail pressure sensor chkt high input p0193

Mine is on too (MIL, with p0193), 2005 freestar. My dealer can't figure it out for some reason? So I went out and bought a code reader, will fix it myself!
Anyways it can be the fuel pressure sensor (approx $100 for part), the fuel pump, or regulator on the fuel line, not too sure what they are worth, and time for labour? I am currently looking for a test gauge to check the pressure in the fuel line to see if it is pump or regulator or sensor. Hopefully your service guys can run a few similar tests and determine what needs to go.

SOURCE: p0193 fuel rail pressure circuit

P0193 - Fuel Rail Pressure Sensor Circuit High Input
The Fuel Rail Pressure (FRP) sensor is a diaphragm strain gauge device in which resistance changes with pressure. The electrical resistance of a strain gauge increases as pressure increases, and the resistance decreases as the pressure decreases. The varying resistance affects the voltage drop across the sensor terminals and provides electrical signal to the Powertrain Control Module (PCM) corresponding to pressure.

Strain gauge type sensors are consider passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow.

Voltage that is dropped across a fixed resistor in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.

The FRP sensor measures the pressure of the fuel near the fuel injectors. This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each combustion cylinder.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine will not start

Possible causes
- Excessive resistance in the circuit
- Low or no fuel
- Wiring harness connector of the fuel pressure sensor
- Fuel Rail Pressure Sensor
- Fuel Pump


Hope this helps (remember to rate this answer).

SOURCE: how to fix codes p0190 & p0193 fuel rail pressure sensor codes

The two codes are both about the fuel rail pressure sensor. I would check fuel pressure with a gauge first.
If pressure is low try the fuel filter before anything else.

Fault Code Definition P0193
  • Fuel Rail Pressure Sensor Circuit High Input
What does this mean?
The Powertrain Control Module (PCM) needs to know the fuel pressure at all times so it can effectively control the fuel injectors and deliver the optimal amount of fuel into the engine's combustion chambers for maximum power and economy while maintaining the lowest tailpipe emissions.
Code P0193
indicates that the signal from the Fuel Rail Pressure Sensor and/or its circuit is too high, indicating a fuel pressure condition that is abnormally high.

Getting p0193 code for my 2005 ford freestar se


P0193 is "Fuel Rail Pressure Sensor Circuit High Input"
Meaning: Car's computer is reading input voltage from the FRP (Fuel Rail Pressure) sensor as
voltage out of the acceptable range, because the voltage is too above the acceptable range.

assuming you are running gasoline...

check for fuel in the vacuum hose of the FRP sensor after running engine at idle for 2 minutes. if not, check fuel pressure. Check fuel pressure by connecting a fuel pressure gauge to the Schrader
connector on the fuel rail, which you will find under a small (black, usually) plastic protective cap.

If the fuel pressure is indeed too high, your fuel pressure regulator has gone bad.

if fuel pressure is good, check voltage between Sensor connector Vref (Pin#3 LB (light blue)) and
Signal Return (Pin#4 GY/RD (gray/red)), which should be 4.0V-5.5V with key ON.
The acceptable voltage range from the FRP sensor to the car's computer is 4.0-5.5 volts.
What the P0193 code is saying is that the voltage from the FRP sensor is over 5.5 volts,
and therefore it's "High Input."

If voltage from the FRP sensor is bad (out of range high, presumably), then replace the FRP
sensor and reset the OBD-II code.

If the voltage output from the FRP sensor is also good, the car's computer is kaflooey, so
you'd need to replace the car computer (which is costly), so replace the car's computer as a
last resort.
