Causes and Fixes Ford P0191 Code: Fuel Rail Pressure Sensor Circuit Range/Performance

[@beagleboy5424]

this is such a thorough, clear and direct video. thank you very much for making.

[@dw1384]

thanks so much for this video! i have a ford escape 2008 v6 fwd and my car started losing power and would start jerking back and forth while driving for over an hour going 100km/hour. engine light comes on, scan it when i get home and got this code. used your advice and got a new fuel rail pressure sensor and fuel filter. car drives like a dream and gas consumption is proper! code came back today so now i’m looking to get a fuel pressure tester now 😅

Ever get it fixed ?

[@woodrowproductions5199]

I have a 2007 Chevy Monte Carlo SS and the battery will go all the way to 14.8 volts and drop as low as 11.8 I need help I just bought a ECM I haven't installed it yet I really need help.

Okay So in my car a 05 ford five hundred I wad getting 89.6 Fuel pressure and car did not want a disconyet the sensor it would saying it's at that 89.6 pressure. Then I had a friend plug. The sensor back in pressure went down to around 3940. And was running fine but if I go to start it, I'll have a problem. Again and and i've already replaced the FRPS and the fuel filter, plugged, Coil packs, EGR But no matter what I've done. The car would start and then shut off unless I disconnected the wiring why

I had this show up after driving in a deep puddle. What could the error code mean in this situation? Truck won't start

[@radtap]

Might be the control module

[@anticommunistalpha]

That control module is as low to the ground as it can be. It corrodes gets holes and then driving it through a deep puddle could get water on the chip itself. Absolutely check that fuel pump control module first.

I have changed the driver module fuel pump and filer new plugs fuel rail and fuel rail sensor and it's still pulling the fuel rail pressure sensor on the code idk what to do next got any idea

Any luck on what's wrong? I'm having the same issues

[@goodvrsevil737]

IM HAVING THE SAME PROBLEM WITH MINE,I TKINK THERE IS A ISSUE WITH A OIL PRESSURE SENSOR ,TELLING THE PCM TO SHUT DOWN THE FUEL PRESSURE! MY TRUCK RUNS FINE FOR A COUPLE MINUTES, THEN IT IDLES DOWN RUNS ROUGH AND DIES, ONLY CODE I GET IS P0191. A 2006 F150 4.6 MY ONBOARD SENSONR TELLS ME TO CHECK GAUGES. I LOOK A THE GAUGES AND THE OIL GAUGE IS AT ZERO. WHEN IT RUNS FINE IT AT NORMAL. AND OIL LEVEL IS JUST FINE. AND PO191 HAS NOTHING TO DO WITH OIL. MY PRESSURE SENSOR HAS 2 WIRES COMING OFF IT I BELIEVE ONE GOES TO PCM THE OTHER TO GAUGE,

[@jakemckeown6322]

I'm having the same issue and can't figure it out. I've changed everything and still throwing this code and dying

[@goodvrsevil737]

@@jakemckeown6322 by chance did you check and see if the alternator is throwing out to many volts

[@m.p.4032]

Any outcome or updates?

[@robertbutth7690]

Truck runs for awile then Shuts off i clear the code and It will again wat Causes this

ANY LUCK IN FINDING THE CAUSE?
