Check the vacuum hose for cracks from that fuel rail pressure -temperature sensor to it's source. You may have a vacuum leak when the engine temperature is hot.
P0191 is a code for the sensor being out of normal operating range. also check the connector for corrosion but is less likely.

I would try checking the IAC (Idle Air Control). Especially if it stalls when shifting from drive to reverse or reverse to drive. If you have a OBDll scanner I would hook it up and see if you get a reading. Good Luck!

Bummer deal. Assuming there is no code, check the throttle position sensor and the cam sensor. The throttle position sensor may have a bad spot at the idle position and not give a reading -in which case the cars computer, confused would stop the engine.
Upon restart, the gas pedal would be in a different place and the car would run. ...Also, the "cam sensor" would cause a stall now and then as it begins to fail for the same reason, and stop the engine. Both can be checked with a meter. The parts store can provide both. A cheap fix - by elimination, before paying for expert help.

One other, more common cause of stalling are sticky valve stems. Dirty valves, stay open a bit longer, and that - like a front door ajar allowing wind in, with valves will drop vacuum and kill the engine. My method is always clean first. That way the bad part shows up better - if the cleaning was not the answer. This particular tune up treatment for dirty valves is this one many people love, from Mega Power. The link details the simple install to do a very complicated tune fix - no other product I found can do! Hope this helps. Link: http://www.auto-tune-up-and-repair-options.com/Tune-up-Products.html

I would say it may be your fuel pump getting ready to go down.

Could be a couple of things. Fuel injectors, fuel pump, vacume leak, cloged exhaust system, ignition coil, bad fuel in tank. I dont know which engine you have. Try putting in staybilizer in gas tank. May have moisture in gas.When it is running, does it run skooth? Also check air filter.Check internet for recall on your car also. May need a mechanic to plug in a computer to check error codes. If there are codes, they can check problems. Hope this helps

I had an 07; mine was a hybrid; quit running; stop; turn off the key; turn back on start right back up. Drive until it did it again. Garage said it was thermostat; and needed 4 computer updates that no one did. Had these things done; no more problem. turns out it was a recall issue for 05 thru 08. Church lady had an 06; also hybrid; this happened to her a few months later; I told her it was a recall; she took it to the DEALER; and they fixed it no charge, because of the recall. Don't know if it applied to non hybrids; as you do not say yours was one. The cost for me was $1075, getting no where with Ford on this, since I took it to a "Christian Brothers" garage. Also I had no idea about the recall til I got an E-mail about it; about 6 months later.

I have a 2006 Ford escape need help repairing intermitting P0191 code problems


P0191 - Fuel Rail Pressure Sensor A Circuit Range/Performance , Description: The comprehensive component monitor (CCM) checks the fuel rail pressure (FRP) sensor for an acceptable fuel pressure. The test fails when the fuel pressure falls below or exceeds a minimum/maximum calibrated value for a calibrated period of time. Possible Causes:
  • High fuel pressure
  • Low fuel pressure
  • Damaged FRP sensor
  • Excessive resistance in the circuit
  • Vacuum leaks
  • Low or no fuel
Diagnostic Aids: A FRP PID value during key ON, engine running of 138 kPa (20 psi) to 413 kPa (60 psi) is acceptable. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test DD .

Intermittent P0191 error code


I had a similar problem that turned out to be dirt contaminated gasoline. The "fix" was always to replace the fuel filter but it would not stay fixed. In particular, each time I started having problems it was after I let the gas tank level get low.

What I did that you can consider was:
  1. But a new fuel filter.
  2. Get a 5 gallon gas can.filled with fresh gas.
  3. Get some cheap gasoline proof container (or several containers) for waste gasoline.
  4. Make a "vacuum cleaner" out of an electric in-line low pressure gas pump, some low pressure gas hose, and a couple of pieces of copper tube, 20 ft of two conductor wire, and two alligator clips. It connects hydraulically copper tube to suck out the gas tank, fuel hose, pump, fuel hose, copper tube to go into the gas can. The wire and clips are to hook the fuel pump to your car battery.
  5. Drive the car until the fuel level is low.
  6. Remove the fuel pump module.
  7. Vacuum the gas tank into the waste gas container through the opening left by the fuel module. Try to get the dirt off the bottom.
  8. When you have vacuumed all you can get, stop awhile and let the dirt settle in the waste container.
  9. Vacuum the gasoline from the waste container back into the gas tank. Vacuum high in the container so the dirt stays in the waste. Try to wash any dirt in the gas tank to below the fuel module opening.
  10. Stop a while and let the dirt settle.
  11. Repeat vacuuming and washing as many times as needed to get the tank clean and empty.
  12. Inspect the tank interior with a mirror and flashlight looking for rust, dirt, etc.
  13. Replace the fuel module.
  14. Install the new fuel filter.
  15. Pour in the new gasoline.
And hopefully you are good to go.

Ford escape code p0191


Possible causes
- Low or no fuel
- High fuel pressure
- Low fuel pressure
- Faulty Rail Pressure (FRP) Sensor
- FRP harness is open or shorted
- FRP circuit poor electrical connection
- Faulty Fuel Pump
- Vacuum leaks
P0191 Ford - Fuel Rail Pressure Sensor Circuit Range/Performance P0191 Ford 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.

You need the Ford dealer to run an active test on the system, it will cycle the fuel pump on and off and return problems found with the relay or other circuit.

Hi. I have a 2003 Ford Focus LX. A few weeks ago, I was driving back to Florida from South Carolina. About six hours into the drive, my car stopped accelerating. I would push down on the gas pedal and...


Diagnostic Test code (DTC) P0191 has a generic description which reads "Fuel Rail Pressure (FRP)Sensor Circuit Performance"

This code sets when the Powertrain Control Module (PCM) is monitoring the fuel rail pressure sensor signal under certain driving conditions. The FRP sensor varies return voltage to the PCM to indicate the fuel pressure at the fuel rail on the engine. DTC P0191 sets when the voltage received from the FRP is above or below the expected "range" or "threshold".

The possible causes of this code are:

> High fuel pressure
> Low fuel pressure
> Damaged Fuel Rail Pressure Sensor (FRP)
> Excessive resistance in FRP circuits.
> Low or no fuel

With all of that said, I would recommend that if you have more than 30,000 miles on your current fuel filter, I would try that FIRST. Replace the filter and clear the code. If the code returns, then diagnostics will need to be performed to find the actual cause.
