Locate the fuel pressure regulator. Check if its fuctioning. Hook up a fuel pressure gauge, and make sure it is within specification, if it is within specification, the fuel rail pressure sensor is not accurate and must be replaced.

I want to no this code for a ford explorer, gas problem, code p0193


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.

I have a mitsubish L200 triton with acceleration problems and give an error P0089.How to fix the error


code p0089 refers to fuel pressure regulator---performance problem===causes --fuel pressure regulator--- mechanical fault
check the regulator operation as it controls the operation of the fuel pump as well
At this point I would be considering a new regulator or checking any wires connected to it

What is the fuel suction valve? fuel pump? You never stated a year. Did you replace the fuel filter? P0089 is generic code for a fuel problem. What was the fuel pressure? Did the pressure hold for 10+ minutes? What are the symptoms?

I have change pressure sensor DENSO 6100 on Nissan X-trial 2005 It was p0089 error code now I have two p0089 and p1275


code p 0089 refers to fuel pressure regulator---performance problem===causes fuel pressure regulator---mechanical fault
code p 1275 refers to heated oxygen sensor (HO2S) 1--response time===causes--- HO2S--fuel pressure--injectors--intake air leak--exhaust leak--MAF sensor
as the pressure regulator ( fuel pressure) appears in both codes I would be paying attention to that unit first

P0193 - fuel 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
help.png Help with thisSymptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Engine will not startP0193 DescriptionThe 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.P0193 Information for specific makesP0193 FORD

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.
