just going down the road with my 2001 ZX3 (5,000 miles on it) and the check engine light has come on, anyone on here experience that on such a new car?

Codes? what do you mean...sorry Im not a mechanic type so bear with me.

My wife was going down the road right past the dealers, so she brought it in instantly.
Its not a red lite, but the organge check engine lite that is on. They cant get it in until friday. They said its completely safe to drive in the meantime.

Its a stupid reminder for you to change your oil. My GF's cougar does the same Shiz. Mine focus only has 2000 miles so I haven't gotten it yet. If you take the car to ford to change your oil, they'll reset it. If you change it , drive it for about 100 miles and it'll prolly turn off.

I started my car w/ a loose ignition wire, light came on. Stayed on after I fixed it, and reset like 100 miles later.

the oil is not even due yet. They dealer just checked the oil to reassure me that it was fine. They claim its something electronic or whatever.

Is it true there is a red engine lite, and orange one? the dealer said mine is orange which means to me I can drive until Fridays appt.

what is the code thing ?

Couple of things:

1) Is your gas cap on tight. In some situation's, with some cars, a loose gas cap can cause the check engine light I believe

2) In my previous car, when new, I put in premium gas (which I never do anymore, it's a scam unless your manual calls for it), and not far from the station, the check engine light came on. I was told, whether or not this is true, that cars that are to run on plain old 87 octane gas can be fouled up by the premium stuff

Just curious if either of these two things may apply to you.

Your check engine light comes on to tell you to have the dealer do a PCM Quick Test. The PCM is the computer that monitors and drives all the systems. Sometimes it will, and sometimes it may not, display on the dealers equipment something called a DTC or Diagnostic Trouble Code. If your dealer checked it and said not to worry till Friday, then I wouldn't worry and go see them on Friday. It can be one of a hundred odd codes. They will check it, fix the problem, or if it is a code that came on for something like the wrong octane gas or some sensor wire that fell off, then they will simply reset the PCM, the light goes out, and you are on your way.
There is no way the computer knows if you changed your oil or not so don't worry about that suggestion.
Unless you have an after market chip or some heavy duty mods to your motor, you are wasting money and not doing your engine any favors by burning Premium gasoline. The Zetec is designed for 87 Octane, use it. Don't worry about whether you caused any problems by using it; you didn't. It may or may not have set off the light...only PCM test will tell the tech that.
Hope this answered your questions.

Yeah, you haven't done anything to damage the engine. Not to start the whole 87 vs premium debate, but 87 (from a regular gas station Texaco, Shell, etc) has the same additives to protect and clean your engine as premium. So as long as your manual says to run 87, which the Focus does, do it. Otherwise your just throwing away money. Don't feel bad, I did the same thing once.

just took my focus into the dealer today. Got the call just now, they seemed like they didnt want to go into much detail about it. They said the check engine lite is now off, but they needed to order a part (electronic part I assume). they mentioned it will not leave me stranded anywhere.

anyone know what they might be talking about? Like I said they seemed to be reluctant to tell me exactly what this part does when I asked. They just said "its under warranty you wont have to pay a cent".

Maybe when I get there they'll explain it more.

I took my car into Ford today to have the CEL checked. Service manager told me it was the DPFE sensor that regulates the EGR valve and that it was no big deal. However, none in stock, of course. Will be un-Focused for another day!

Although, I have mine back today!

If you make some mods to your car, then you may need a higher octane gas. In stock condition name brand regular will do it, just fine. If you use a chip in you ECU, then you will most probably need 92 octane fuel. Although before I installed a chip I ran 89 octane and the car felt better and the mileage increase aboput .5mpg. So now you know.

Has anybody gotten recall on the DPFE sensor that regulates the EGR valve for 2001's. I checked the Blue Oval News site and there was nothing referencing this part...anybody aware of this?

Let us know...Thanks!!!

fridays here still no part. Oh well!

anyway, going down the road last nite, and the car is going at a very steady speed and a slow rate about 35mhp on a completely level road. The car seems to be pulling back than springing forward ....very,very slightly, just enough to feel, but not move RPM gauge much. any clue if this has to do with the sensor that may be bad on my 2001 Zx3??

This is an sensor problem, i got this sensor replaced twice in 20 month (10k km and 50k km), looks like something wrong with a design. I also feel some interruption iduring the driving (very-very small and only on a low speed).
probably next time won't be under the warranty, so if somebody has the info about the location of this sensor, i'll be really appreciate (still waiting for the repear manual to be published).
this warning has nothing to do with oil change, but emission only

Mine has had it's DPFE replaced already. it's a 2001.

gottijr:

That feeling your getting is the sensor going bad and the EGR malfunctioning which probably caused the CEL.

regarding Higher octane fuels:

The higher the octane, the higher the temperature you need to get it to combust.

Our engines are designed to take 87 octane. Anything higher will not completely combust which leaves you with wasted fuel.

With a chip to advance the spark will be able to take advantage of higher octanes and therefore combust the fuel completely. If you use 87 octane with a chip you may experience detonation.

i can tell you its not the gas cap theres another light for that someone stole mine. it could be an o2 sensor or anything so just take it in to the dealer

my light came on anly when I turned my audio system up for a few minutes...I assume it's du to strain on the alternator.....I reset the cpu and it was off until I turned it up again.
