    Dang. I needed to see it fixed. I have the same problem. And my cheap scan tool can not turn it on. Also can I have the car? I would rather have a wagon. You can always use another place to sleep.

  9. Avataaar/Circle Created with python_avatars Gold News says:

  12. Avataaar/Circle Created with python_avatars Dennis Abrameit says:

    Everyone needs to get their sinner valve fixed or else well you know what could happen

  13. Avataaar/Circle Created with python_avatars B61 Mack says:

    Eric, what company or websites do you use for your wiring diagrams and information about codes and what throws them?

  14. Avataaar/Circle Created with python_avatars Gamingex Artisty says:

    So is it just the diverter valve or is it Silenoid too? I have same code an no way to check with light but I’m pretty sure pump is working I’m basically at the part u figured it was one or the other

  15. Avataaar/Circle Created with python_avatars charles owens says:

    you do a great job thanks

  16. Avataaar/Circle Created with python_avatars W M says:

    Can't check air filter, "lifetime" air filter

  17. Avataaar/Circle Created with python_avatars Working mans restorations says:

    This is second time you have helped me out. First time was my s10 steering column harness… This one helps with same Fusion codes

  18. Avataaar/Circle Created with python_avatars mike abang says:

    Great vid we’re can I buy the valve and silinod

  19. Avataaar/Circle Created with python_avatars Russell Foote says:

    you have so many good videos, I wish I could pick out make, model and yera span. I mean you have a really long list and good chance you've done one like mine

  20. Avataaar/Circle Created with python_avatars Richard Bambenek says:

    Man that engine compartment is packed tight. It looks like a basket of coat hangers.

  21. Avataaar/Circle Created with python_avatars Mark Ash says:

    Would love to see you tackle a trans problem with one of these. I have a 2013. They have the 6-speed "automated manual" trans in them and, the clutch, at least, is a POS. Have to have all kinds of special equipment to work on them. I wouldn't wish one of those on you for anything. Thanks for another great video and, as usual, excellent work.

  22. Avataaar/Circle Created with python_avatars BRIAN VELTRI says:

    Omg I laughed my ass off !!! 😂😂

  23. Avataaar/Circle Created with python_avatars Ronald de Rooij says:

    I would be annoyed as a customer to pay for all the diagnosis time, as the customer specifically said what was wrong with the car.

  24. Avataaar/Circle Created with python_avatars tommy wilson says:

    What scan tool was able to tell the computer to turn ( i found i had a bad vaccum solenoid so far )

  25. Avataaar/Circle Created with python_avatars MIKE CONT says:

    Great diagnosis video……thanks for taking time

  26. Avataaar/Circle Created with python_avatars J. Chris Beck says:

    I never knew until now that ford changed the engine orientation in the focuses,,,, my exhaust is in the front as opposed to the intake in front on this car you are working on.

  27. Avataaar/Circle Created with python_avatars Mike Chiodetti says:

    WOW! BATH TIME! Where's your rubber duckie? Only one better than this was the time you opened the HVAC (undercar) drain and like a garden hose, the water poured out! "There's your problem lady!" There should be a way to purge these systems from time to time. Great Video, can't forget that! I wonder how many parts will need replacement after that water gets cleaned out?
    Obviously, not much time was put into "possible causes!" Many times I've had to run my own test to verify operation or non operation, as the case may be.
    When is Part 2? Thanks for sharing this. Oh ya. What would happen if all that water got in the engine? HMMMMMMMM!

  28. Avataaar/Circle Created with python_avatars DIYinVideo says:

    I have a 2007 Ford Focus 2.0 Hatchback. I have the codes P2257 – P2258 & P0412. I have replaced the secondary pump, the solenoid, the Relay to the pump and the vacuum diverter valve. I cleared the code and drove around a couple of days and the engine light came on again with same codes. The pump works (blows air) when I jump it. Doesn’t sound like pump turns on during cold early morning start.
    Do you have any idea why the pump will not turn on when starting up first thing in the morning?
    Is there something I’m missing? Any suggestions?

    yo u are the best trouble shooter i have seen u r not a guess mechanic which is very cool been watching a long time its my first time responding thanks 4 the knowledge

  30. Avataaar/Circle Created with python_avatars DirtyFingernails Auto says:

    mightyvac sells a complete rebuild kit for those , IIRC its on amazon easy to do and cheaper than a new one

  31. Avataaar/Circle Created with python_avatars DougSolomon50 says:

    OK the blower and fuse both work when I connect with the wires- so – does that mean the check valve is bad??

  32. Avataaar/Circle Created with python_avatars John Ferguson says:

    We drove our Toyota Camry wagon 375,000 mi without any trouble. Then we sold it to a kid who put in a new set of valves and drove it another 100,000 mi. That's the clear difference between Ford and Toyota.

  33. Avataaar/Circle Created with python_avatars carl brandon says:

    KOER Test should work the pump bidirectionaly.. That was quite a surprise when the water blasted…hahah  would you be worried about the air pump motor having water intrusion and failing in the near future?

  34. Avataaar/Circle Created with python_avatars Hola! Michael Spisak says:

    Nothing like a little unexpected facial to get a laugh or two Eric !!!

  35. Avataaar/Circle Created with python_avatars tousleytim says:

    so the valve was working why did the water not get pushed into the exaust?

  36. Avataaar/Circle Created with python_avatars Matt Wagner says:

    Diverter valve facial…LOL!

  37. Avataaar/Circle Created with python_avatars Kevin Woodcock says:

    The happiest of Thanksgiving wishes to you and your family Eric. I hope you enjoy the day.

  38. Avataaar/Circle Created with python_avatars jimbola77 says:

  40. Avataaar/Circle Created with python_avatars Joe Mikos says:

    Great video as usual Mr O! The people need a live feed video please.
    Thank you

  41. Avataaar/Circle Created with python_avatars ryzo mcgregor says:

    I would imagine most of the manual gearboxes are sold in UK and Europe as Automatics are less popular.

  42. Avataaar/Circle Created with python_avatars xcirca6 says:

    Always interesting to see the car you own worked on

  43. Avataaar/Circle Created with python_avatars R Miller says:

    Nice 👍 video as always. How often do cars have to be inspected in your state and can you maybe do a video sometime of what all has to be done ✅ in order for the vehicle to pass the state inspection, what it costs, is it a scam etc?

  44. Avataaar/Circle Created with python_avatars Michael Luscher says:

    Have you considered using FORScan for FoMoCo products?

  45. Avataaar/Circle Created with python_avatars Todd Rodriguez says:

    Lanch tools great got me out Alot of jams😀

  46. Avataaar/Circle Created with python_avatars Michael Roblin says:

    Awesome Eric!

  47. Avataaar/Circle Created with python_avatars John Slesinger says:

    Im still trying to watch all your videos. I was a garage owner and a heavy equipment service manager. You are a much better mechanic than I ever was. I like how you do things right while still doing the right thing for the customer. Great to see your family too.

  48. Avataaar/Circle Created with python_avatars DRealitG says:

    Is the SMA amazon store not working right now?

  49. Avataaar/Circle Created with python_avatars AJ Osmani says:

    Another great diagnosis.
    What OTC scanner are you using and would recommend it?
    Thanks E.O.
