Question about Mercury Monterey

2 Answers

Code P0193 I have a code P0193 coming up on my van. I don't quite understand what the Fuel Rail Pressure Sensor Curcuit High Input means. Is this something I can repair myself or do I need to take it to someone?

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.

    It was the fuel pressure regulator. 5 dollars from the junk yard. needed a good grip phillips screw driver.

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.

Fault code p0193 solution


code p0193 refers to Fuel rail pressure (FRP) sensor -high input Possible causes ---wiring short to positive--- FRP sensor. I would replace the sensor with a genuine unit as after market units have different parameters and the cpu may keep bring up the code.

P0193 - Fuel injector supply Rail Pressure Sensor Circuit High Input

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
P0193 Description 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.

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.
