Ford Focus: Check Engine Light

consider taking it to AutoZone or the like. most of them will scan for free
and tell you what it says.

I didn't know they would do that. Thanks.

Or check it yourself.

The Focus has a built-in test mode where it will tell you the stored
code. Instructions can be found here:

This just happened to me for the 2nd time on my 01 ZX3. Both times it has
been the DPFE sensor and both times after it was fixed the check engine
light comes on a day later for something else. First time was a fouled
spark plug. The second time I will find out tomorrow.

Thanks Tony.

Well it's tomorrow and the mechanic didn't engage the connector to the
sensor all the way and it worked loose.

If it works. My check engine light came on yesterday.

I don't get a DPTC code with this technique.

Good luck.

The 
that. 

An extremely common problem: someone else here might nicely supply the
drill-down URL for
more exact descriptions. Or just google on 'ford focus check engine light'
or even 'focus DPFE'
(I searched the latter more than a year ago when the issue seemed more ..
burning...) to get a
sense for how common ... (how nebulous?). ...

Last week was at least the fourth time for this happening on my wife's '01
SE. (I have decided
to start checking the mechanics' name badges at our well-used and -abused
local Ford
dealership -- all these visits under warranty, BTW, at no charge to us -- to
see if one of them
might be named Godot ... Hopefully... ).

The time before, the mechanic was reportedly ecstatic that my wife
remembered and could describe exactly how she was braking/clutching/shifting
at the moment the light came on because "that was
going to help" him figure it out. The time before that, the problem that
tripped the engine
light was reportedly not the fuel filler cap being badly seated, and not the
fuel tank itself leaking
in any way, but some tiny leak somewhere between the gas (petrol) cap and
the fuel tank. I no longer remember the cause of the very first one. I only
remember that I was driving it that time, and expended enough panic for both
of us then, and for all succeeding occasions...

I will admit to great laziness here, in asking about the URL someone else in
the thread supplied
for what the error codes mean, a site I haven't visited: If you/we/I have
these codes -- general knowledge,
so to speak -- shouldn't/can't I just assume that this (reputable)
dealership's mechanics are running off just to see the same codes each time,
also? If so.... then, what? (!?) ... However he himself calculated them,
the last mechanic (i.e., the 4th time) again, reportedly, said that more
than 40 (different) glitches could trip that light.
