I had a very weird occurrence today in my 2005 Expedition with the 5.4L.
I was driving around in Dallas and all of a sudden lost throttle response.
I also got a message "throttle control failure" in my message box. I killed
the engine, restarted it and got throttle control back. But now my check
engine light is showing. I then continued my trip to Houston without event
(but with a little worry). I have 78K miles on my expy and I got 18 mpg
on the way home (about average for 70+ mph).
Does anyone know what happened and how serious it is ? I plan to visit
my local repair guys (non-dealer) if the check engine light does not reset
in a couple of days.
This likely isn't the kind of problem that you want to leave to chance. It
may be something simple (even as simple as an improperly installed air
filter) ir it could be something more complex. There will be DTCs stored in
the computer to assist your tech.
There were at least two technical service bulletins that dealt with
electronic throttle control concerns as well..
Yes... independant shops have access to TSBs... but there are a couple of
First, the shop needs to be willing to spend money for adequate
documentation. There are a LOT of small shops that try to work with no
manuals - no factory bulletins and only OTJ (on the job training). You
cannot do that with any amount of success on todays complex cars. Second,
the list will generally be a little behind the dealers access as aftermarket
subscription updates would likely only happen quarterly.
As Ed mentioned... find a different dealer... as a dealership tech, I get to
use the finest Ford dedicated scan tool available... BAR NONE. I have access
to the latest manuals and documentation... nobody has anything more
current... I have access to the factory hotline, a group of engineers that
have areas of specialty that can assist with difficult diagnosis or act as a
Occasionally, a customers frustrations (due to having a new car that
SHOULDN'T have problems) over car problems can bubble over and have that
customer become....... contrary... Occasionally, a customer will walk into a
dealer service department with unjustified animosity.
What would make a dealer tech so much worse than an independant shops tech?
The better training? The more advanced tools?
The fact that they could not fix my brakes on my 2005 Expy. I
took my expy to Helfman Ford for a normal brake job. I left
there with a brake pedal that went to the floor. I complained
and they said "Oh, that's normal nowadays". I then took my
expy to Midas who told me that my brake system had air in it
and that my discs were very roughly ground (you could see the
grooves in the discs). Midas bled my system and I had them
put new discs on it. Life is much better, not perfect though.
So, would you frequent this dealership's service department ?
Absolutely not.... But that doesn't mean I wouldn't go to a different
I don't work at Helfman Ford... My job at the dealer I do work at is to make
sure that you dfon't have that kind of experence... ever... but if something
sneaks through the system, my other job is to stop it in it's tracks.
There are good stores and there are bad stores... everywhere.
Your bad experiences (and the good ones) are built by people just like you
FWIW... I offered you good advice and you are returning??????
Sadly the tools and equipment - and even the training, don't make the
man. There are incompetents in any trade, at any level. Some
dealerships breed incompetence, some reward it, and others attract it.
Some dealers will not pay a competent man fairly, will not treat him
fairly, will not allow him to avail himself of the available training,
etc. etc. etc. So they end up with a bunch of incompetent mechanics
working under an incompetent service manager, for a dealer principal
who really doesn't give a rip, as long as he's making money. He is so
short sighted today's gain is what counts, regardless what it might
cost him tomorrow.
THAT is what, to a large degree, has put the american manufacturers in
the position they are in, sales-wise.
