Thanks this fixed my wife's 2014 Ford Fusion that was starting to hiccup a little bit and stall at red lights sometimes. I had no check engine light and no codes but this fixed the idle issue.
Thanks, Steve! I've been dealing with the same issues different codes. I've had to change the canister purge valve and a sensor that looks exactly similar to the one you're testing just exactly diagonal from that one so now I'm can do some tests to see if the sensor you tested can be the reason why my car keeps stalling, sometimes even when I'm driving... so I thank you again, let us cross our fingers and hope this works!
Hello Erica, did you fix your issue stalling issue? I’m having a similar issue on my 2013 Ford Fusion. It’s done it a few times, and I hear a buzzing sound for a short period when it’s going to stall, but only thrown out a engine code p144c which is vacuum leak on canister purge valve. I want to know if you were able to resolve that with the replacements you listed.
Whitewine12 man bro it was a headache and a half but we found out it being a heater hose tee that melted off inside the vacuum hoses cause the car to malfunctions. After having to replace everything that the sensor indicated the problems being but now it was a simply 30 buck heat hose tee. I’d check yours just in case if not I replaced the high and low fuel pressure sensors and it ran a lil better. Lmk how everything goes.
Whitewine12 I’ve had P144C code and stalling on my 2013 Ford Fusion. I addressed the P144C with a brand new purge valve assembly (easy DIY). I also had a failing fuel sensor replaced and that solved my stalling issues.
Hey guys long time no talk just wanted to let you guys if you still have issues with the fuel senors. Try checking the heater hose tee located on the right hand side closest the the engine bay. Their we located the plastic pieace melted off in the hoses after replacing the part the car drove fine. Ive had to replace the evap valve; low and high fuel pressure. Turns out it was their more of an issue then we thoight. After replacing the heater hose tea with a more stable part conpared to the standardized part. I was still having probelms with the ac conpressor. It was causing the engine to lag cauing the cars rpms to fluctuate but thats here nor there. Ive already rendered the car due to the fact i forgot to check the car faxs and there being like 20 some odd recalls on that particular car. So life + lesson = learned.
I’m noticing the exact same issue in my mom’s 2014 Fusion - Titanium model. It stalls at idle intermittently and it’s really irritating her. She’s had the vehicle for about 3 years and not one mechanic has given us a solid answer.
Samething with my 2014. No chk engine lights on so cant get a code but stalls intermittently. Changed hi pressure sensor an low pressure sensor and its still happening
I just had this happen two days ago, confirmed the same code today and all the same info but what was the fix? Since I've seen the tests you did which im going to do on Monday in class I want to know what to fix or replace for this issue ? Hope its not an expensive fix
I wonder if the LP sensor was damaged by the high pressure pump? On BMW specially the N54 engine those LP sensors will read incorrectly but hardly will create any problems. Usually low rail pressure was caused by the HDP pump. So it needed both the HDP and LP sensor some severe cases also the injectors.
You can't compare the N54 engine to the Ford engines; the fuel systems work differently; specifically, the HPFP on the N54 is chain driven, and it's regulated differently. It appears from the video above (need to verify) that the HPFP on the Ford is electric. Steve mentions that the HPFP is a pulse width modulated pump (probably to do away with a fuel pressure regulator). A check valve probably prevents HPFP discharge from entering the inlet from the low pressure fuel pump, but I haven't seen a schematic yet. I'll bet this is just a bad batch of faulty sensors produced by the manufacturer.
Steve I have a 2009 Mercury Mariner 3.0 V6 and I am having the exact same symptoms. When removing the air cleaner, I do not see this low-pressure sensor anywhere. No check engine lights and no codes but the exact same symptoms! Everything I read says the fuel pressure regulator is in the fuel tank. I put a new throttle body on but still have the same symptoms. Would you have any idea what be causing my problems?
15 Fusion SE 2.5 L is different than the system shown here. Having a intermittent cranking problem and when I do manage to crank / start it the shuts off. Dies. A couple of mechanics said it could be crankshaft sensor. Got more that twenty codes.
@@VirginiaBoy703 long story short, we never found out what it was. I took it to three different shops the last being an auto electric place. First one came up with 20 codes and he thought it was bad computer but I wanted to be sure. Second place they again scanned it came up with 22 codes. They suggested an auto electric shop so I took it there. He didn’t find anything wrong with it and they tried to pull up codes and nothing no codes. Ran perfectly normal. He said take it home nothing he could do no charge. It’s been running fine not one single time it didn’t crank or stalled out. Mysteriously it was just fine. Been a week since that happened last Thursday.
@@VirginiaBoy703 and if you take it to dealership even they might be able to tell you what’s wrong. My experience with another car- they gave me two different repairs both costing me about $600-700 and if the first repair didn’t work then they try the second repair.. but I was going to try them if that last shop couldn’t help me. But car working normally now. Very mysterious
2014 ford fusion SE 1.5 1. Jerks when trying to accelerate at slow speeds 2. Has hard time going over slope super slow but engine sounds smooth Like just doesnt react 3. If driving 70mph wont accelerate have to press pedal slightly but wont detect it until ive preesed for a while so it jumps from 2nd speed to over 3rd speed and engine will sound like full action super forsed
More than likely to end up replacing both fuel sensors 1 is under the manifold in the front and the other is up by the battery near firewall im pretty sure. Cause they as a pair tell the car it has way to much fuel pressure when it doesnt the sensor are failing so the cars will trim themselves completely out of fuel.
My car stalled than shut off and won't start. The computer told me it was a crank sensor and cam sensor. I changed the crank sensor already it didn't start I've odrred the cam sensors do you think this will work?
No codes come up on mine, it stalls when idling but has happened when driving too rpsm jump around then it dies. Happened 2 days ago then I drove it for 2 days then nothing happened…
No stalling is different then automatically shutting off. Mine is having the same issue. Those start back up when the gas pedal is pressed. When stalling the pedal does nothing.
Very thorough diagnostic video!👏
This is the only video on TH-cam that makes sense for me. Thank you!
5:44 thank you very much for your explanation!!! Very good work
Awesome video with great information
Great video very informative and to the point.
Starting to research as my daughter's 2014 Ford Fusion is doing exactly what you described! Thanks, this gives me some things to check!
Did you get her vehicle fixed? I’m having same issues on my 15 Fusion.
THANK YOU VERY MUCH FOR THIS VIDEO . YOU ARE A GOOD MECHANIC .
Thanks. The part number is BU5Z-9F972-B or CM-5250
Great video you did a good job thank you so much I will subscribe keep up the good work GOD bless
Very helpful tip. I’m a young mechanic who’s learning and don’t want to be part changer.
Amazing video
You Just Saved my Bacon!! This happened 3x today! Twice yesterday! Thanks for the Help!! Thanks So Much!
Did the low pressure sensor fox the issue?
@@e.brandon5694 Yes it Did! Car doesn't stall out anymore going on 2yrs. Was like $120 for the sensor.
Very informative and helpful video! Thanks for sharing!
This goes for Lincoln MKZ as well … thanks this helped me

Does anybody know what the pressure should be for the high pressure pump?
thank you
do you have to reprogram the throttle body or not
Just happened to me and the wife today in traffic thanks I'm a do it yourself kind of guy came straight home and started the search
I have the same problem also wen I put gas I changed the sensor the one is located by the engine puli what sensor did you changed?
Changed every sensor and high pressure pump still cutting off?

Hi Steve, I have ford fusion 2010 and I am experiencing the same issue. Any suggestions please ?
Low rpm fuel pressure sensor. I just changed it.its the only sensor that doesn't shoot a code
I've had this same issue randomly shutting off
I I'm having the same problem with my 2014 Ford fusion
Did you figure out what your problem was?
Me to
Hello, What part number did you replace with?
Did you find out?
@@strickstang85 yes but ill have look back and find it
More than likely to end up replacing both fuel sensors 1 is under the manifold in the front and the other is up by the battery near firewall im pretty sure. Cause they as a pair tell the car it has way to much fuel pressure when it doesnt the sensor are failing so the cars will trim themselves completely out of fuel.
Sir nice video . I have a code p2004 on 2006 ford fusion SEL. Any help.
Hi everybody 👋🏾
I have a 2006 Ford Fusion SE 3L 6 Cylinder and I’m dealing with the same issue.
Look at the voltage 5 volt reference 3 volts should have been a red flag
My car stalled than shut off and won't start. The computer told me it was a crank sensor and cam sensor. I changed the crank sensor already it didn't start I've odrred the cam sensors do you think this will work?
What was it
No codes come up on mine, it stalls when idling but has happened when driving too rpsm jump around then it dies. Happened 2 days ago then I drove it for 2 days then nothing happened…
Were you able to resolve the issue? I have the exact issue on my 15 Fusion.
Mine is doing the same thing at 77,000 miles
Mine is with 45000
High pressure fuel pump
Why did I buy a Ford Fusion if all I’m being told Is it could be this and it could be that answers And not a solution to the problem
The problem with this posting is, thatyou didnt prove that what you suggested actually solved the problem. That's a difference maker.
did you find the solution?
Y’all do know 2013 and up Ford Fusion engine shuts off to save gas when coming to a complete stop it’s a feature called auto start stop
No stalling is different then automatically shutting off. Mine is having the same issue. Those start back up when the gas pedal is pressed. When stalling the pedal does nothing.
Mine is a 2014 and does not have auto start stop. It is an optional upgrade, not standard
Modern cars are built like absolute fuckin junk.
Why didn't you mention what engine this is? Kinda pointless video without mentioning that critical information
4 cylinder bro it’s pretty basic
@@VirginiaBoy703 your mother

Puts 4 different 4 cylinder engines in these. 1.5, 1.6, 2.0 and a non turbo 2.5.
