Lunch is over and it is time to find out what in the heck is causing this fuel tank pressure sensor to go on the fritz! Is it the ECM? Is it EMI? Is it a chaffed wire in the harness, or is it something completely unrelated to the EVAP system all together? Let's find out! -Enjoy!

Eric, my respect for you, you don't know how mach I would like as good as you I been a mechanic for over 30 years and never been as good as you are, I have lern alot from you, I love the Way you work congratulations eric..
Eric you are the best, I would't never thank p/s pressure switch be the problem, you sould be sooo proud of your self, you are so impresive mechanic.
Persistance is your driving force.
You did the right thing by talking with somebody else and taking your time in diagnosis. My hats off to you for doing the job right.
Good job, I really like your videos! I’m watching them all. You are a credit to your profession.
Little luck once and awhile is a good thing
Wow! Excellent diagnosis! I'm guessing not many shops could have resolved this and that's the scary part for car owners today.
Excellent learning process. Thank you for the candid version of the story and not glazing over all the trials and tribulations along the way. Great work checking off the boxes and exploring the variables. You sir are one of the greats in a dying breed of real mechanics. Most are just parts changers now a days. Cheers !
I'll merely affirm what everyone else is saying – you're an incredibly smart, diligent, and thorough diagnostician.
Why don’t you have the hoodie dark gray and true royal in XL so I can buy them
Eric – Nothing under the hood scares me , I will troubleshoot and try to repair any problem on my own vehicles. I am not a professional vehicle mechanic BUT will still say to anyone – YOU ARE A SUPER DIAGNOSTIC TECHNICIAN. That being said , I would be like a first grader of auto repair if I were to even try and make a comparison of my skills to your abilities. It is nice to get LUCKY , as you say , once in while – and , yes ,it is humbling , but certainly none of us are know it alls – that is something we all have in common. In this video YOU still found the problem – and will say you still dig in – you are like a pit bull , you certainly are NOT just a simple parts changer – as I think even many other professional shops – would have just installed a new ECU as there diagnosis , only to find out it did not fix the problem. Nice to know , that you ALWAYS go the extra mile , as is sometimes said , to be VERY THOUROUGH , before condemning an ECU – not that even the ECU does sometime fail – but generally it is rare – as ECU are super sofisticated and very reliable – generally speaking. ✌️✌️
When you are troubleshooting a problem and say you don't know why some trouble is happening – this is also what makes you a SUPER technician – YOU ARE
HONEST 👍👍✌️✌️🙂
Maybe it has to do with the alternator reaching its peak voltage?
Persistence does pay off. Good job.
Thanks you for making this video. I just had the same problem on my father-in-law's 04 escape. I didn't think it was the sensor or a vacuum leak since it would let me clear the code and it would take 5 days for the check engine light to come back on. I never would have guessed the power steering pressure switch. That's just out there. Tested the wires with some straight pins and a multimeter. Sure enough just passed 3,000 the voltage drop down to 0.4 or 0.7. There was a p1650 (KOEO) for that power steering switch. I got it fixed today. Thank you for your help.
Humiliating..? I know of an ER Doctor who sent a kid on a helicopter to a childrens hospital because he slept on new, unwashed blue sheets… That's humiliating… I'm betting there aren't many people in the tri-state area that could have fixed this ford… well, at least as much as a ford can be fixed, amiright…
Imagine how many poor sobs buy that ECM.
The 3krpm was always the cookie. Good job Eric.
Insane
4 years late to the party…. This is the kind of stuff that happens to me daily, I’m pretty sure I’m the last resort person… not giving up makes you better than most, no shame in this game. Doubt 99 of 100 dealerships would have found it…
its better to be lucky than talented……its a pretty good video…..far far better than i could do……the basic problem is that you weren't organized and you had a slapdash approach…….not once in the entire video were you in control of the situation….you should have had a better organized testing plan and just tested one thing after another after another after another……you sorta worked around the edges of a testing plan with the parts cannon………………..in the end walking out the door at the end of the day after 8 hours of work you finally had your first original idea about what to check…….'what else happens at 3000 rpm'………..pretty good video …..if it was my car i'd still not know what was wrong 3 months later, but i have neither luck nor talent
Wow the power steering Pressure Switch Is bad and that 12v Switch caused the major issue that is crazy 🤔 makes sense when it shuttering very Nice find Eric O @SouthMainAutoRepairLLC
That is what I see too. " an intelligent and dedicated worker not give up, save your customer alot of money, then sharing a lesson learned." Erik you did a great job and I appreciate you sharing your experience with me.
Hi Eric, Your the best . I am learning something new from you.
Bullshit!! It's not luck when you knew what to look for. Pure genius Eric!! 👏
Persistence pays off in the end.. great job.I hope Ford pays attention to your channel they might learn something or two about what they have created.
You may have misunderstood how the power steering switch work. Did you have the knowledge knowing that the power steering switch is involved in the cause and effect related to the conditions that brought on the onset of this failure. If you'd had known how the system worked you would not have been able to figure out why it didn't
I can not believe what I just saw! you call yourself a mechanic? Everyone knows when you have a bad windscreen wiper, you always check the lugs on your spare first! Or when you have a low tire, make sure the air filter is in tight! "Just kidding!" One thing did kind of suprize me! when you went to the junkyard, you have some sort of after market device on the the dash! What???
Most unusual issue. Good for you to stick with it and keep on with the great mind you have
Impressive, that is not lucky to me, as an instrument technician work in oil field you won my respect.
AWESOME JOB ERIC, TECH IS GREAT WHEN IT WORKS, YOU THE REST,THAT IS WHY OLD SCHOOL IS THE BEST.
My Toyota RAV4 has the same time system run by solenoids and oil pressure thanks for the help on diagnosing that kind of stuff it's my daughter's car so tell her to change the oil all the time
You are a Rockstar Eric and very few people would have gone to the lengths that you did without a complete emptying of the parts cannon and thousands of dollars spent
for nothing. You used you brain, eyes, tools, knowledge and called the Jedi Master and made the right diagnosis without wasting the customers money. You are a true craftsman and
your passion for the trade is evident in all that you do. Thanks so much for all your videos and your teachings for those of us that are not exposed to these rare gems every day.
NICE JOB!
Eric, i watch every single one of your videos. No matter what its about. Ive never commented before. You said you are not the super tech everyone makes you out to be. Im going to have to disagree. Introduce me to another tech that would EVER consider power steering while dealing with an evap code. Yes, this particular diagnosis may have had you running in circles, but one was bound to trip you up eventually. Guess what? You STILL figured it out. You may feel like you got lucky, but your thought process is what got you to that lucky break. Its great to be humble. But you are a god among men when it comes to diagnostics.
Very interesting.
its all good, u cant know everthing with all the baked in weird ass timers triggers self test shit u never know what the thing might b doin without actually reading or bein explained the process electronics n computers r for sure takin over cars, i bet theres goin to b a counterfad in years where ppl try to do with away with as much electronics as possible, like back to kickdown cable n carburetor n mechanical fuel pump baby :p lol while its cool n all i prefer electronics
Some days it pays, some days use a big hammer
I had a similar issue with a boat motor. It was. 6.2L GM based IO. It ended up being the pressure switch in the power steering circuit causing running issues at 3,500 rpm’s. I figured it out after having at the Marina a 1/2 dozen times.
Were you ever able to explain how the 5V ref was being polluted on the harness side and was generally cleaned up by unplugging the DPF? Was the trash on the 12V power steering pressure sensor going through ground to the DPF and then showing up on 5V reference which ultimately affected the FTP sensor's 5V ref and causing the bogus signal at 3000 rpm? It was interesting following the 5V reference pollution from the harness side attributed to DPF…and then all of a sudden you tracked it down to the power steering pressure sensor (using the 3000 rpm trigger analysis). But never heard an explanation of the 5V ref pollution related to the DPF (and fixed when it was unplugged)…
As Wayne would say in Wayne's World: " Were NOT worthy…were NOT Worthy"…In other words you are a Jedi Knight when it comes to trouble shooting…I'm always impressed !!!!
I wonder if a frequency choke or a special diode in line could be use as a diagnostic tool when you got close to the end?
Don’t sell yourself short man. You ARE a super tech. You found the problem in the power steering pressure switch because you were relentless in tracking down the cause. Yeah, you did all the regular stuff testing the circuits involved without finding the problem. That’s because the bad component isn’t part of the circuitry your logical testing checked. Give yourself credit for a job and fix well done! You deserve a trophy🏆.
Eric great video everybody needs a bit of luck sometimes keep up the good work
Great job figuring it out. I love that you don't just throw parts at a problem.
So bizarre. Another case of you know what it's doing, but not why it's doing it.
Just like the dude in Dirty Harry I gots to know.
I know this is late, but good call.
