2006 Ford F-150 5.4 engine: code P0191 fuel rail pressure sensor circuit range / performance

First step is to change the fuel filter and test the car. If the problem still occurs: The fuel pump driver module was corroded through from salt and was malfunctioning. Bought a new one and runs great. Problem fixed. See pictures below:

This is why salt destroys cars.

SENSOR 1 ??????????? There is no sensor one involved here . After replacing all those parts an not fixing the problem ,suggest you take it to a qualified repair shop. The proper thing to do would be to do the diagnostic's for code P0191 . Do you know what a factory diagnostic flow chart is ? How to test electrical circuits ?

Anon, Trouble code P0191, You may need a good tech. with scan tool to read and test system.
  • Fuel Rail Pressure Sensor Circuit Range/Performance,computer see's signal from the Fuel Rail Pressure Sensor and/or its circuit is sending erratic readings, indicating a fuel pressure condition that is abnormal. Problems could be out of gas, leaking fuel, faulty fuel pressure sensor, bad wire or plug in circuit,fuel pressure regulator, the fuel pump could be faulty also. Check the attached links,instruction and guides, Good luck

P0191 and p0113 on 2007 ford tauras


Someone has no idea how to diagnose a ford,
I would say

PO 113--Intake Air Temp Circuit High Input
PO 191--Fuel Rail Pressure Sensor Circuit Range/Performance

I wouldn't be installing any parts, until you find the real issues
there,try a different shop or dealer

A fuel pump & cps sensor & give it back to you half
fixed
That was nice & typical of all the people that come here

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.
