P0191 can be a difficult code to track down, but should not be ignored. If the fuel pressure reading is low, than you’re going to need to figure out if it’s the fuel pump or fuel pressure regulator that is causing P0191.

If the manual fuel pressure reading is normal, then you know that you’ve got an issue with the fuel pressure sensor (or the wiring going to and from it). If the reading seems off, you’ll need to manually check the fuel pressure. You can also use it to check the fuel pressure reading as you drive. Or, right after heavy engine load when the fuel pressure isn’t recovered enough for a proper idle.Ī good scanner can help you look at the conditions that were present when the code was set. This is typically noticed under heavy engine load. You’d notice hesitation and stalling as the fuel pump struggles to keep up with the demands of the engine. If it goes bad, it can restrict the flow of fuel to the point that P0191 can be thrown.įord F250: Bad Fuel Pressure Regulator DiagnosisĪ bad fuel pump would act exactly like a bad fuel pressure regulator. The fuel pressure regulator is responsible for making sure that the amount of fuel pressure that reaches the fuel rail is at a constant level (which will be less than pushed by the fuel pump). Does it look broken or damaged? Is the connection to the sensor solid? If it looks bad, it may need to be replaced. Take a look at the wiring harness around the fuel pressure sensor. Wiring issues can cause P0191 to be thrown. If it goes bad (or if the fuel pressure really is out of the normal range) P0191 can and will appear.Ī bad fuel pressure sensor can force the vehicle to overwork the fuel pump, thinking that it’s constantly starving for fuel when it is not. The fuel pressure sensor is responsible for telling your F250’s ECM/PCM what the actual fuel pressure of the vehicle is.

Here are the most common issues that cause P0191 to be thrown: This can lead to the engine dying when coming to a stop as well.įuel mileage can suffer when the air/fuel mixture isn’t correct. If the fuel pressure at the injectors is inconsistent, it’ll be really hard for your F250 to maintain a steady idle speed. P0191 can be caused when the fuel pressure regulator is bad. If it runs too lean, you’re likely to have p0171 accompany P0191. If it runs too rich, you may get black smoke and P0172. Without a reliable reading from the fuel pressure sensor, your F250 may end up with the wrong air/fuel mixture.

If there isn’t enough fuel pressure getting to the fuel injectors, the engine may stall out or hesitate in certain situations. Here are the most common symptoms of P0191: Stalling

When P0191 is present, there typically are noticeable symptoms. P0191 is typically caused by a bad fuel pressure sensor, fuel pressure regulator, or an issue with the fuel rail pressure sensor wiring harness. This is a generic code, which indicates that it has the same meaning for the Ford F250 as it would any other vehicle. It indicates that the fuel rail pressure sensor is receiving a signal that is outside of its normal range.
