A Valuable Resource
I'm posting here because here is where I found a major lead in my EEC-IV path to education.
I know it has been quiet in here for a while, but it's time it was re-awakened.
I have been looking for information about what my eec-iv was seeing and then what it was actually controlling, and how.
I know this is an old thread relatively speaking, but I only located it last week, and as a result, I found a Scantool with three cartridges, one for my 1994 Ford Explorer 4X4 Limited which works perfectly, a GM cart. and a Chrysler Cart. All this and in new condition in all the original boxes for just $49 + 12 for shipping.
I have followed the on-screen prompt and was able to read all the sensors just as shown above by Glacier991's post. I have listed them all and will probably build an Open Office spreadsheet to list, define, and clarify them all.
There are a lot of features that I do not understand yet, but I'll keep reading and learning.
About 3 or 4 years ago, this car would not run. I had let my mother take the car as a daily driver and she found a "highly recommended" local mechanic to work on it and $3000, all sensors, and 3 computers later, my X finally came back to life though it seemed to still be ailing.
Finally I said enough of this guy and took it elsewhere, and after about two hours, I got the car back running like new.
Well, I am here to say thank you to all of you who contribute so much to this forum and its members.
And a special thank you to Glacier991 for this particular post as well as all the other contributions you make. I have all these numbers, so now I will be studying more to understand the meaning of each number. The newest of the replacement eec's was obtained from NAPA as I did a search on the part number and in the Napa listing, it is stated that this new/re-manufactured/rebuilt EEC is 'flash re-programmable'. That may come some time in the future, but I will have fun doing the research and learning the process.
My Explorer has just over 176K miles with the original engine and transmission and I'm doing everything I can to keep it well maintained and safe. I read, and plan to re-read Glacier991's Transmission chronicles on the "Bulletproof A4LD Rebuild" because I know, one day, I'm going to feel something wrong, but for now, she's running great thanks to all of you.
