My mother in law and I thank you, so simple. Great straight for clear speaking well lit video. Saved over $300.00 with actual original equipment!
Excellent video. I just changed the fuel rail pressure sensor on my Mercury Monterey minivan. Quick fix. Keep the videos coming, I have used your channel several times to fix my vehicle. You have saved my bacon more than once.
I always start here when I am looking to do work on my Explorer for all these little safety tips that others don't seem to feel are necessary. Thank you for these videos.
The problem with diagnosing faults is the ECM will adjust Injector fuel input on O2 sensor data. Thus if the Pressure Sensor is Over estimating the rail Pressure then less fuel gets injected creating a lean burn. BUT The 02 sensor picks up lean, ECM increases fuel injection to compensate the lean condition. And your Long Term Fuel Trims rise, the car runs normally as the defficiency in fuel input has been quietly rectified. The Only clue you get is high LTFT with no apparent reason. Your mileage doesn't change as you are not using more fuel, just an adjustment to input the correct amount of fuel. And the LTFT will likely be similar across all engine loads, whereas vacuum leaks Trims are worse at low loads and get better. Even if the fuel regulator on a high pressure pump is faulty, the rail pressure sensors feedback to the ECM increases the regulator operation to get the pressure up, so you are unaware unless the regulator goes really bad and can't keep up. So if you have high LTFT across all engine loads, the car runs normally, the MAP sensor is fine, then the fuel rail pressure sensor is the likely problem. Now if you have to pay the cost of removing the intake manifold to get at the sensor to test pressure test it...well you may as well put a new one in while you are there...and maybe test the injectors as well. Especially if your car has done a lot of miles.

Gidday Brian. After the repair; is the process of Clearing the PCM's Memory" a necessity. There was no mention of post-repair. Many thanks mate - you provide an invaluable service to the average Joe.
I’m sitting in the dealer right now watching this video. I was curious about this thing and how to change it. They just charged me $350 to change it. I actually watched them change it. It was a new girl and she did it less than 10 mins! Ugh! I could have done it. This video was very helpful.
Wtf
Abdul Mumin yeah. I was so ticked off. That’s was a lot of money. I could have done it myself. :(
Well I had a similar problem to yourself. I went and bought the part. When my mechanic went to change it he told me the part that's all on looks quite new basically he made the call without even checking. In the end he noticed there was alot of worn out wiring that he basically taped up cleaned out the RD valves charged me $70 at first I thought it cost me so much more. Maybe I paid him $20 more but to be honest I got a refund on the unwanted part so far so good.
🤣😂🤦🏻♂️
Thanks for the video just had to replace my fuel rail pressure sensor for my 2005 Ford Focus after the engine light came on and detected that my sensor was faulty. This video worked and saved me from going to a mechanic. Great and easy steps and I had my new sensor installed in a few minutes. My car now runs so much better than before.
Mechanic tested over three days and $900 dollars later. I had placed sand bags over rear axel in trunk. That weight caused pressure on wiring that caused P0191 code. Go figure. Moved sand bags off wiring and it is fixed!
Hey man, 5yrs later this video helped me out! Thank you!
I so much appreciate your efforts in providing professional information to the many of us who , although we have good mechanical skills, would never take on such a "previously" difficult / impossible task. With your info and links, I purchased a NEW Bosch part on line for $70 (Canadian), purchased a code reader for $80.00 (Can), and replaced the fuel sensor in less than 30 minutes start to finish. Error cleared. When, will my For* dealership realize that an estimate of $400 part + diag fees + install ... is simply unwarranted. I didn't want to purchase the DEALERSHIP, I just wanted to clear the CheckEngine light. Thank you very much and keep up the great videos.
Thank you for this video. I like your methods. I can see you have done this many times. Much Thanks! Reno, NV
Great video man typically I have to look at three or four other videos to have an idea of what it is that needs to be done but that was not the case here you gave a thorough explanation very clear very well done
Very well explained, good detail,, well done. I've got mine ordered but from the link you posted below, but it wasn't near as expensive, like $60, which was cheaper than you thought it was, and it said Motorcraft. Thanks for posting, JohnG
I can’t say I’m thankful I am that you made this video. Watched another video and changed my fuel rail sensor.. when I started it fuel was leaking like crazy and I had no idea what to do. Watched your vid and just loosened the screw to let the pressure out and my car is running again (was stuck in a win Dixie parking lot of two days). Cheers mate and thanks so much m!
To fix: "Idles worse when warmed up."
2 problems on my ZX3. 1. Collapsed PCV line at idle. 2. Fuel rail pressure sensor diaphragm was leaking gas INTERNALLY. No visible leaks outside. It's internal. This extra gas
was flooding the car at idle. I replaced the coil, plugs and wires too but that problem remained even after the vacuum line PVC line was replaced. The fuel rail pressure sensor leaking internally was it for sure because it leaks gas into the intake manifold via the vacuum line attached to it. Thusly, flooding the car at idle when warm with too much gas. Rough idle when warm is now fixed!! No more rough idle. That pressure sensor controls the fuel pumps speed. If faulty, you get too much fuel pressure AND gas leaking through the diaphragm. Car runs rough at idle and/ or dies and because its too rich.
What kind of fuel pressure were you getting? I'm getting 65psi on my scan tool.
@@macknumber9 That's what I read too.
Thank you! Trying to fix myself and have 0 knowledge. Thank you for all the extra tips and tricks.
Thanks for the clear instructions, did everything as instructed in the video, and now my car is running like it's normal self again.
how was it running before
Thank you very much, I was able to fix my Dad's truck with your video.
Thank you very much. Your explanation is so clear easy to follow. I was able to fix my truck without any complication.
What happen is still the same no star
Thank you for the great video!
I noticed that it was a 4 wire sensor, every piezo sensor that I have seen on all makes is a 3 pin. VRef, ground, and signal. Is the 4th wire a Fuel temp signal line?
The reason I ask is because the sensor probe looks just like a thermistor. Thank you FordTechMakuloco
Question, i have a 99 mustang GT and i am having a “High pressure” fuel issue that is intermittent. New pump in it. Has been doing this for years. Do you think my aftermarket cams are messing with the vaccum?
FordTechMakuloco.
I have a P0087 fault on my 2012 Focus 2.0L GDI. fuel line pressure is 4 bar but the car still limps. Could it be this sensor?
Very professional video, thanks for posting. When you broke the vacuum by removing the sensor starting at 4:31, fuel poured out the open fuel line on the upper right. I suppose most wouldn't have that line apart. It would have been nice to see how you proved the sensor was bad -- diagnostics will always be the weakest point for those of us who learn here on the net.
I have a whole video on the diagnostics for this this sensor.

Thanks!

Great video. I have a 2000 ford focus sohc, it seems to have low fuel pressure at idle, could it be a faulty fuel pressure sensor? It runs good when driving, rpm are low at idle and at red lights. Any suggestions will be appreciated.
Keep up the good work bud. Excellent teaching!!!
I just replaced the FPS on my 2006 mustang but when I tried to accelerate its doesn't go as fast as before. I dont know if I did something or didnt do it correctly. Any thoughts?
I knew I saw something leaking over there! Anyway man, Love the videos. Super easy to understand. I and everyone else appreciates it. Keep rolling!
What was the reason for changing the sensor?
Question for you ;
I have an 05 Escape with a 2.3L engine that has excessive fuel in the combustion chamber and exiting out the exhaust.
I have codes P0183 and P0193 ... any help would be appreciated.
Anybody else just scroll through the comments to see which ones Brian comments on?? Any extra info from Brian is golden..lol
What tool is needed to replace the low fuel pressure sensor on a 2013 Escape Titanium 2.0l?
Hi Makuloco, What were the symptoms please ? Mine 01 2.0 zetech jerks before, at and after stop sign - almost stalls -no codes - new fuel pump filter and idle ? Thanks
fordtechmakloco how u doing I have a quick question I have and 05 ford explorer xlt 4x4 and the 4wd the front is trying to get stuck any tips
Would this help regain fuel pressure without changing the fuel pressure regulator because I have not any pressure within the vacuum line
I have a 2010 ford focus and my check engine light is on I checked it at auto zone and I got a p0451 code what part is that most likely associated with
Hey Great video, can these sensor and sensors in general randomly work (intermittently) ? my ford seemed to work after a shop replaced a fuel pump and and fuel pump module 2006 e150. and then 2 days later I lost power again and stalled. and stayed in that mode until I was towed home. Then it seemed to work again. and a day later lost power again. Also would one of these sensors prevent me from starting it?
Great video. Thanks for taking the time to put it together.
Thanks for the video! how many sensors does a 07 ford explorer have?
I purchased the sensor yesterday for $8.59! They emailed me this morning saying they made a mistake and canceled my order haha
Thanks so much for the great tutorial. I happen to own one of the vehicles where the FRPS is hidden under the manifold (2007 Explorer 4.0L) so I need to get to it before I can replace it. I would NOT call myself a backyard mechanic - I'm a mom on a limited budget. I have a Haynes manual but it is obviously written for those with more automotive knowledge than I have. Do you know of any tutorials on how to remove the manifold cover? I need pics or a video because I don't know (yet) what most of the components are. Any references would be GREATLY appreciated!
Also check the driver module in the trunk. I had a 2010 Mustang that produced a P0191 code so I changed the FRP. No luck. Then checked driver module and found it under water because the drain troughs were clogged up and the spare tire well was full of water.
Would this be the same process for a 2005 Ford Escape V6 3L. Ford is telling me that the upper intake has to be removed?
What is the function of the vacuum line on top of the sensor ? Mine snapped off and I'm not noticing a difference in performance.
I've seen GDI engines with over 500 PSI fuel pressure. Good safety advice in this video Brian
+Ozzstar
I have experienced GDI fuel pressures over 4000 PSI running and over 1200 PSI residual pressure with key off.
Hey would this sensor replace the mechanical fuel regulator? I have a 2001 ranger 3.0 v6 and it seems that this ranger does not have a mechanical fuel regulator. So I'm gonna look for this sensor.
Will the CEL go out on it's own after replacing it or does it have to be cleared?
Thanks for the lesson; it was very well done.
After replacing and checking for leaks is it normal to smell gas inside the car.
I also had the defrost on if that makes a difference
Do you have an issue with buying faulty parts these days? I have installed two of these in a couple weeks both were supposed to be OEM from ford for my 4.6l. Had a code p0193, now I am having a PO182 which is related to the same part…wondering if counterfeit parts may be at play…maybe I’m being paranoid.
I'm getting p0182, did you find a fix for this??
Awesome video man! Very in-depth
How about on a ford 6.7 powerstroke ? I got a p0088 fuel rail pressure too high . Do you think it could be a fuel pressure regulator on the fuel rail? Or the pressure sensor?
Hey Brian. Have looked at all your 5.4 videos. Saved me a lot. From ball joints to upper control arms to front diff and rear fluid services. Bought the aftermarket, plugged it in, and it stumbles and missed so bad. How do I diagnose to make sure this is the actual problem before buying OEM?
Do I use the same method on my 2005 Ford Focus
05 crown Vic..I had a CEL for this item. When I pulled out old one, there were two washer shaped cups sitting down in there? The O-ring came out with old one but after that,that’s what I found sitting down in there...any idea?
Is there a way to pump out the fuel tank through the fuel rail on these newer Ford's?
How can I check for fuel pressure? My engine doesn't have a Schrader valve for me to attach gauge on to.
Did you use dielectric grease on both the terminal and the o-ring, or can you use Vaseline on the o-ring? and can you use a sensor from a Junked car to replace a damaged sensor?
Thanks for all your help and take the time to make videos ....
Would a bad fuel rail pressure sensor affect the gas meter,miles to emty data?
2007 ford explorer fuel rail sensor, replaced twice, replaced connector, still having issues with trouble code P0193, and need further insite to other remedy to resolve this issue. my code reader when vehical is operating the pressure stays constant and does not flutuate at all at 72.?? PSI throughout idle and increased engine throttle. any suggestions on what else should be evaluated for correct function.
Does that sensor work for 2014 ford fusion ecoboost 2.0t as well ?
Excellent Video!! Thanks Brian!!
Great video. I am actually getting a P018B and occasionally a P018C error. Will replacing this sensor correct my problem?Thanks
I have a 2003 Windstar with 3.8l. Morning start is multiple cranks and then it finally starts. No rough idle or lack of power during the commute. Shut it off and if you need to restart within 30 minutes, it fires up right away. Leave it for like an hour and you're crankin a few times again to get it started. But then it's ok for the drive... Any ideas?
Had a lot of things done to my truck now one of the things that that's coming up is the fuel pressure sensor. I don't want to keep spending money on the truck is there a way to clean the sensor for testing to see if that's the problem?
Went to the junkyard U-Pull it and looked for an Escape to get this part part for mine but could not find then come to find out, it was used on nearly all newer Fords!! I felt stupid walking all over that yard for an Escape when any Ford would have had it haha Amazon wants only $18.99 but AutoZone wants $119! Crazy!
(2007 Navigator) i have changed pump...COP plugs starter ....truck runs well but has a looong crank now...sometimes 2 attempts to start ...long enough where folks ask if I'm good. Could this be my problem?...causing it to loose pressure in the line until it rebuilds????
I've got a noise in my 1995 ford ranger 2.3L. Can't really tell where from. If I upload a video do you think you can help me figure out where the sound is coming from
Need to empty 2012 f 150 2wd supercrew gas tank....
What is your suggestion???
2013 Ford Escape SEL. Engine shut off while driving... it "slowly died" while driving. Mechanic says "it's the fuel rail sensor switch". This sound right? And would it be about the same set up as your video?
I replaced my sensor but lost the O ring in the chamber. Any tips to clean this out?
THANK YOU.......For making these videos and helping the avg Joe with a toolbox at least try to save some money here and there..
i have a p0453 on a lincoln navigator 2004, were can i fine the sensor, iv look everywhere cant seem to find it.
I have a 2005 Mazda Tribute which I have been told is the same as Ford Escape. The problem I'm having is that I get different miles per gallon for every tank full. On one tank full I will get 19 MPG, then the next I will get 15 MPG, then 13 MPG, The 10 MPG, then 15 MPG, Then 19 MPG, and so on. Could this Sensor be causing that? If not, would you know what it could be?
Is there a special tool or way to remove the circlips holding the fuel injectors to the fuel rail? I am really struggling
2000 ford explorer engine light on, p0174 p0171 lean codes, replaced vaccum hose on air box housing and till code
reappears ?
My 03 mustang gt just died in the driveway, code was P0190 what do you think pressure sensor or fuel pump? also amazon does not have this motorcraft part for my car
2005 Montego
Other than the fuel rail pressure sensor code PO191 going off numerous times and changing the sensor 7x in 3years (2018-2021) I ended up with car eventually going into safe mode.2019-2020 several times. Eventually it no longer reported codes it just had no power and no acceleration.
I changed ECM with a new one with 2 keys from flagship 1 as my key would lose sync many times needing battery disconnected for 10min. Losing ECM link.
Was going to change main catalytic converters but when I cut down the rear converter it was broken gravel on the 1st disc and appeared clogged.
After the ECM and CAT change it's running great. Power good.
No key problems. Was able to sync 1 of my old 2 keys.
81.262 miles
Check rear cat. Replaced with WALKER 93237 ULTRA CAT using the forward fitting from the old cat cut flush.
My 2004 escape 3.0 doesn't have one of those anywhere I can find, it's just not there anywhere on the engine likevit is in all the videos. So what do I change to fix a p0001? Is mine integrated into the fuel pump?
On my 98 Ex v6 4.0 SOHC i hooked up my scanner to FORSCAN and i'm getting a 0psi reading even when the car is on. Starts up every single time the only issue is that i've been stalling at intersections and red lights a lot more. A rolling idle. No codes. New PCV valve,cleaned MAF/Throttle, new IAC. I'm hoping my stalling is something having to do with the fuel delivery and the 0psi reading on fuel pressure might be the culprit. Am i on the right track or does this sound more like a vacuum leak?
I have a merc sable 2002 and the P0193 fuel rail pressure sensor A circuit HIgh came up on my scanner I replaced the pressure sensor and my car still stalls and dies I don't know what would be another option?
I have to replace that on my car shortly what type of Grease did you use
I have a 2013 Fusion SE 1.6L with Ecoboost and I see nothing that looks like that and cannot find a diagram or video anywhere. Any advice?
Gracias excelente explicación y fácil reemplazo de la pieza, buen dia
I need big time help loco i need to find the idle air cotrol valve on my ford taurus 2008 sel please can you help me find it
i have a 07 f150 5.4l i have two codes p0148 and p0191.... i replace a new fuel pump and new fuel rail pressure sensor two years ago. what do you think about that? help me please bro
Does it also work with the diesel version?
What years are this sensor installed on? I can not find this on my 2011 f150 5.0
Does a 2002 expedition with a 5.4 have this type. The engine is dripping fuel while idling. It drips from the rear passenger side of the engine.
i changed that in my 04 mercy mountiaeer 4.0 and now am getting p0193 ? ??? i brought it at napa for 60.00 ???? its under the intake lol
Would this be what the part looks like for a 05 ford focus?
Help please, I just bought a Motorcraft sensor for 2008 Ford Explorer number, (CM-5229) it’s a 4.0 engine. The first one I took out was a Bosch , and the second one I bought was a Bosch also. I’m just comparing the Motorcraft (I just bought)with the reading on the 1st bosch and I noticed, that the Bosch has the same numbers and the Ford logo and they’re made in Germany. So what’s the difference??
Great information and very thorough-thanks, man!
Any suggestions for a P0193? I replaced the sensor and fuel module, and it's still faulty.
Would this cause a No Start on the Escape?
Is this part on a 2014 Focus SE? I keep getting a P0087 code and I replaced the HP fuel pump, fuel pump, fuel pressure sensor.
What are the symptoms of a failed sensor. I’ve been fighting lean bank codes and very low power on a 2005 3v 6.8. When it runs horrible I can unplug the sensor and it runs good again. Can I leave it unplugged till I get the new sensor?
is there a way to diagnose whether it's a fuel pump issue or sensor issue?
Looking for information on 2013 5.0l. what attachments are needed for testing fuel pressure? Cant find info anywhere. No Scrader valve
Does fusion 2013-2016 2.5L use this sensor couldn't find any information about it in service manual how would it regulate the pressure then? 🤔
hi man.. i got ford focus 2004 2.0L.. and the problem is P0191 fuel rail pressure sensor, i can't found it, can you show me where is it and what it is?, please.. thank you
