Well now that we all know the answer it is time to FINALLY change the part that failed. Who would have thunk, Power Steering Pressure Switch setting an EVAP code!? Likely won't be the last strange thing we see.... -Enjoy!

Evap system and Power steering pressure switch is the repair Very intriguing and interesting good find Eric O @SouthMainAutoRepairLLC
You sir are the auto wizard
Hey I've had ideas come to me at the most inopertune time. Either way you fixed it. One for the memory bank.
I’m pretty sure that a dealer mechanic wouldn’t be able to figure that one out, but would probably suggest that it’s time for a newer car. Thank you for your persistence.
Definitly one for the books
Well Done! It sure pays to be thorough! A mechanic better keep an open mind and be prepared for anything like you do.
I knew it right away? Because it's a ford!! Haha! Of course the evap. System is connected to the power steering pressure switch?!
So glad you posted this! If you hadn't I'd have never figured out my 2013 f150 5.0 fx4 Air mass was flaking out due to AC pressure switch! Who knew, thank you so much for the work you do in posting these!
You are such an awesome all around guy.
Just had the same problem with my daughters Escape. Would not drop out until steering wheel turned. PPSPS PID would not switch from high to low. Found an article on web regarding this. Feel your pain
Need more that's your problem lady bangs.
Definitely worth a three part video diagnosis and repair. Can you imagine," Maam, the reason your fuel tank pressure sensor illuminated your Check Engine light is because your power steering pressure switch went bad". Yea right! Thanks for the vid.
Excellent diag and repair.
what the 'book' going to pay on that repair…took seconds to r&r sensor????
Honestly I don’t think this was a bad diagnosis at all. I think you did a hell of a job. Still might be suspect of a bad diode somewhere in the ECM.
I have a new slogan for you Eric
-If I can do it, you can't do it.
A+A+A+
Badass
Well done
Should have used some brake cleaner on it. LOL
My gut was telling me there was a dead spot in the tps. I was sure scratching my head when you found the fault in something as odd as the power steering switch. Nice going Eric. Some days ya just have to go with MeMaw.
Persistence of a true genius pays off for customer!
What next… Changing the channel on your TV sets a misfire code? Turn the wipers on and the toilet flushes?
I'm a half-way decent backyard mechanic, at most. This diagnosis would have had me running away, screaming, curling up in a fetal position, and possibly sucking my thumb. Man, not only do you have a lot of knowledge, but sheer grit for hanging with a tough diagnosis.
nice to watch yoiur vidios cause I don't have the cool tools you have or ther money to buy them…you keep me out of hot water with the MRS alot so thank you for that…Keep them coming and yes…I Can Do it
The strangest repair I ever saw on YT was a guy with a 2.4L Malibu that had a lot of miles on it, and suddenly one day he had the “reduced engine power,” “ABS,” “fix the Stabilitrac” and similar money lights come on, which would result in the car stopping and leaving him stranded on his urban commutes to and from work. He tried and tried but couldn’t figure it out, and finally asked his father to go with him so he could abandon the car and his father could give him a ride home, but when they got there his very wise father asked him if he had changed the antifreeze. At first he thought his father had gone crazy, but he humored him, bought the antifreeze and drained and changed it in the parking lot, where he had planned to remove his license tags and just leave the car. The car straightened up right away, the money lights went out, and when he made the video, he had been driving the car again for quite awhile. From other sources, it appears that worn out GM antifreeze becomes a low voltage battery and in the right conditions generates enough electricity to screw up a number of delicate electronic circuits and ruin the drivability of the vehicle. If you have a five year old GM with electronic gremlins, remember to check on your antifreeze.
I still think it is the O2 sensor. It must be. It always is.
I don't think I could have done that one. You barely pulled it off with a lifetime of training and experience.
I watched all of this expecting it be the large intake manifold tube from pcv valve that cavitates when revving up. I saw that this ford had oem one there and was sure you would rev in hard with camera showing it. Interesting it was something else. But my wifes 2001 ford escape has had almost every weird problem that took many hours of reading forums and diagnosing that car. Even had the infamous green wire defect to ecm causing random coil misfires. Anyhow if you already didn’t know ford escapes have weak rubber tube there that is something to know. Enjoy all your vids and Brians mobile1 as well. Hooked on them! Thanks
I think your test rides are the best I love your Gift of Gab oh mother lover crab biscuit and the crusted socket as a bars scene thanks bud
I don't have the drawings, but someone at the factory should identify the method by which the dpt switch noise gets to the evap channel. I can think of a few possibilities.
Always nice to see the proof. Thanks for sharing. Still a bit lost, though, on not having the experience of understanding how to follow all the scope data and such.
Eric I'm very impressed with your conversational tone and overall diagnostic finesse. However throughout have had this feeling like you reminded me of someone. I'm sure you have heard this before so sorry to repeat the suggestion that you are an automotive Beatlejuice! The tone of your voice especially in humorous moments is very much like Michael Keatons in his role as the undead sage. Thanks for the fun all round.
The monitor routine in the ECM might be interrupt driven, which would explain why the entire thing slows to a crawl when that PS pressure input is toggling fast. It was meant to trigger once then move on with the rest of the processing, but when it is flipping on and off the CPU spends all it's time servicing the interrupt.
Wow. I’m a Master tech and I can say that would have ruined me too…your work ethic is refreshing based on my 10 years experience at the dealership. Tools are only as good as the technician using them
Awesome repair!
I think you diagnosed this pperfect. Alot of us including myself would've replaced the pressure sensor and never would've guess power steering sensor good call buddy
Nice job!
that is nuts
Make sure you send that diagnosis to Ford. You might get a footnote in a repair manual…
One hell of a find.
That'a pretty weird. Glad you got it sorted. Thanks for the video.
I do my mostly do my own work. I got tired of taking it to shops that would throw parts at a problem and not diagnose the REAL problem and charge me for each part swap. With OBD2 I can do the same thing and only pay for the cost of the parts, not the labor. The trick is if you have a difficult to diagnose problem is to start swapping out the most inexpensive parts first. Even doing it this way my expenses are less then 1/4 of what I would spend taking it to a garage that does not do thorough diagnosis. Of course channels like this and online forums are valuable resources also. 2001 Ford Escape XLT 230,000 mi and still running well.
So what's the takeaway from this? Is it "when you see a problem like this (the evap system), but everything checks out ok, start looking at other sensor outputs?" I don't have the wiring diagrams, but is the PS pressure switch wiring near the Evap wiring? Is it inductive interference, or was the problem strictly caused in the hard wiring?
Do we attribute this to the "blind hog finding the acorn" syndrome, or good, hard diagnostic skills? Or something in between? Regardless, it was entertaining and educational – thanks Eric O!!!
" YOU DA MAN " !!!!! Great video , Again !!!!! 👍👍
You should be working at NASA.
At least it was the sensor and not a defective PS pump or a rack.
fantastic i love stuff like this i can spend all day doing diagnostics, probably why i'm the asshole that always gets the shit nobody can figure out or doesn't want to deal with
Fords are fun! When I was working at L.A. Dept of Wtr and Pwr, we had some unique problems with the fleet vehicles. One was a computer code for a non operational turbine input shaft speed sensor. Using the NGS, later the WDS, then the IDS, the sensors worked flawlessly, even when the code set. Also, instead of the TSS problem, when the engine was started, foot brake applied, trans shifted to reverse, the engine would stall, like the TCC was on, except it was disconnected. In both sinarios, HOLD ON,……changing the ignition coils and spark plugs solved the problem! One time, with the NGS connected and on flight record, I started the engine, put the trans in reverse, the engine stalled. Fortuneately, I had added the VSS pid with several others. Watching the recording in "tenth's of a second," I saw the VSS show zero (MPH), zero, zero, 127 MPH. This with the foot and parking brakes ON! WOW! Super Truck! Seriously, changed the original 37,000 mile Motorcraft spark plugs and Motorcraft Ign Coils, using OEM plugs and coils,…….no more problem! Like you say, "no idea" when people would ask me. Speculation? The secondary in one or more coils was back feeding into the primary passing it on to the PCM. That higher voltage found its way to other circuits. The PCM cut off the injectors at 127 MPH…….we think.
Anyway it worked. The Ford trainers at the LaMirada training center were at loss for words.
I don't know how many vehicles were repaired that way, but it was LOTS ! !
Gut, or subconscious – or decades of experience and a will to stick it out.
Now that was a NFL Quality Super Bowl Hail Mary right there. Great Case Study, Hmmmm were have I heard that term.
Im in the middle of my own Night Mare as I type, Trying to take it as a Challenge, I will Win darn it.
Wish I had your Diagnostics Tools, Im limited to a Actron and a VOM. But in the end its whats between your ears that counts, as you just showed us………..And a little Luck. ( very little ).
You should go through all your videos and make a play list, and call it Eric's Best.
I dought there's a 100 techs on this planet that could diagnose and repair that problem
