I used to only pull Fuse 11 (for my 1996) to clear the code until I bought the OBDII code reader about 6 months before I joined CEG. When I first came onboard, I had some PM discussions about this. The reason given was the key, if inserted in the ignition, not necessarilly in the "ON" position, would still have power on for the ignition (Fuse 4 is for both DRL and ignition). This is for the 1995, 1996 and also 1997. Now, maybe the 98's (and 99s) were different but the 2000 would require Fuse 6 (Keep Alive Memory) and Fuse 11 (Ignition, EEC) to be pulled. So the answer given for Fuse 4 and 11 would cover all the bases. If you pull only Fuse 11 for a 2000, the car will run the same until it goes through the OBDII cycle and then what it takes for the car (maybe two more cycles) before the PCM turns the CEL off.

I can see nothing in any of the schematics that would substantiate your claim that F4 also needs to be pulled for any 95-99 Contour. F4 is hot only when the ignition switch is in START or RUN for all of these vehicles.
If you have a technical reference that provides other data, please provide it.
The 2000 requires only F6 to be pulled (the circuits are very different for 2K) to reset the KAM.

Why don't you upload your schematic for us? So that we can be educated by a source rather than just accepting that your word is as good "The Word". As far as everybody is concerned, you are just ProjectSHO89 and I am just Tony2005.

There's is no substitute for the factory service docs.

Would it be prudent to remove the egr valve and clean the opening to the UIM where the EGR Valve attaches? Also, would it be a smart to clean the EGR tube? Is that even necessary and if so, would replacement of the EGR tube be an option?

Any thoughts on my last post?????

if you feel there is a reason to then that would be a good idea, I have only ever heard of people needing to clear the passages behind the tb ...
hmm this remind me of an argument I had on NECO the other week ... trying to help a guy with alignment problems, although I was wrong on one part I took the time to post links and definitions and try to explain myself, this one guy could only say I was wrong and never explain himself, he never really answered my question .... in the end all I got from him was he as a certified tech in 1 of 4 states that require certification and that he had an elementary teaching degree but all he could say was I was wrong and have no idea what I am talking about :nonono:
I still hold if you can't explain or explain to someone who knows nothing about the subject in a way thay they inderstand then you don't understand enough yourself ...
oh I'll add that I was extremely ticked since I had really bad luck with a chain alignming my car, I took it to a local long in existance shop and they did it right ... but like I said I posted link and definiations and asked questions and reasoned through the problem ... I wanted to learn if I was wrong and the guy with the education degree couldn't explain more then I was wrong, ****ing idiot ...
sorry I had to vent some as it really ticked me off .... so lets learn here and not fight :laugh:
TBcleaning to help clear EGR passages.

In addition, if you are going to clean the EGR tube, one good way to clean the insides (if it is really clogged up), is to install/attach a TV coaxial cable to a drill. On the other end, fray the cable so that it becomes like a brush. Have at it.
