Come along with Eric & Ivan in this diagnosis as Ivan double checks Eric's original diagnosis on this 2008 Ford Escape 3.0 AWD. It turns out it is not always as simple as replacing the EVAP vent and calling it a day.

    Hey Eric for slag burns or any first degree burn, i use oragel, as a former navy welder i can tell you its works

  8. Avataaar/Circle Created with python_avatars John E. Carr says:

    Another great video.

  9. Avataaar/Circle Created with python_avatars durawins says:

    Also unless your checking fuses you shouldn’t be stabbing around with a test light, a fused meter would be much safer at least that’s what they taught in LMV industries classes. Then again this is just a Ford Escape. BMW or Mercedes big damage can be done. These guys are good tho, I need to learn how to use a scope. Not gonna act like I know how haha

    I’ve def seen the pcm be the cause of this fault on some Audi’s in the past A6 and a TT, they didn’t believe me but I was right lol now I have a 06 ranger I’m looking at, I’m thinking it’s the same thing I’m gonna look again today.

  11. Avataaar/Circle Created with python_avatars AJM patriot says:

    Wouldn’t the purge solenoid have the same fueling symptom?

  12. Avataaar/Circle Created with python_avatars John Smith says:

    To much talk do it first

  13. Avataaar/Circle Created with python_avatars Ramiro Arellano says:

    I have a vent problem with a Chevy Cruze it keeps open all the time you think is the pcm???? Or needs reprogram

  14. Avataaar/Circle Created with python_avatars steven kolegas says:

    Would this cause the bwttery to drain when parked?

  15. Avataaar/Circle Created with python_avatars Christopher Bradley says:

    Well well well

  16. Avataaar/Circle Created with python_avatars Bruce Parnell says:

    And that's why I keep my 1955 f100

  17. Avataaar/Circle Created with python_avatars Gary Jeffers II says:

    Help me understand please. With the evap vent solenoid being normally open, I would expect that when voltage is applied that the vent would close. It appears that during the testing after the PCM was installed after the dealership reflashed it that Ivan was commanding the circuit on which was dropping voltage to 0. I'd expect that commanding the circuit on would result in voltage being applied and commanding off would remove voltage and result in the solenoid resuming its normally open position.

  18. Avataaar/Circle Created with python_avatars Bob Smith says:

    So when you want to hook a computer up upside down you have to hit the connection harder. Thanks. Still, aren't you tempted to examine the old PCM guts to see if the failure shows?

  19. Avataaar/Circle Created with python_avatars Thinman says:

    Always a good diagnostic. Thanks!

  20. Avataaar/Circle Created with python_avatars B.M. Walker says:

    Hey guys I have a 2008 tribute I have replace both the purge and vent solenoids and the PCM and I still have the code P0446
    Any other possibility

  21. Avataaar/Circle Created with python_avatars KRTube75 says:

    I would have loved to have seen you guys open that thing up and examine it.

  27. Avataaar/Circle Created with python_avatars Jay 8a says:

    dude you're gonna make people fry their computers by grounding that test light and pluging it to one of the vent control valve connectors..

    Oops! Old video. I really appreciated the interplay between mr brakecleen and ivan. What's wrong with going back to the gascap??
    Much better billable items for service dept. income (similar to wallet flush). Now owners are sshush, it's a secret (BETA TESTING).

    Thank you Eric! Hey Ivan I guess is not that easy to work with a pretty lady right next to you!!

  33. Avataaar/Circle Created with python_avatars 01hondascott says:

    last year my 2010 escape got a recall for a reason that could cause fumes in the car and they had to take out my back seats to get at something. now i wasn't having problems with the fumes before the fix but i have been ever since. the ford tech said i might be able to smell gas for a little bit then it would go away but it's been a year now, i really don't want to take it back to them because they seem to create problems and not fix any, any input at what i should look at? i should add i only smell fumes when i fill it past 3/4 of a tank, anything below that is fine.

  34. Avataaar/Circle Created with python_avatars Gary Alford says:

    Great video guys, yeah I know how those dealers are! I once had 2 new 2007 chevy 3500 plow trucks that would overheat in the plowing season, the dealer service rep. said we should take the plows off and carry them in the beds between parks, I checked with some guys on a site called BAT Auto and one guy sent me a service bulletin for the exact problem which gave me a list of parts needed which was a new fan clutch that took care of the problem, which was under warranty, now why couldn't the G.M dealer do this ? never trusted them again after that. I gave all of this information to the plow installer who said he had people complaining of the same problem and boy was he ever happy.
