'01 Ford Ranger, RIP 93 X
Due to the continuous aging of our vehicles, inabilities to buy new vehicles, we're all striving to maintain our vehicles, so below is a list I've made of codes, which test condition, and the probable cause. This list is for 1991-1995 Ford Explorers and Mazda Navajos. May also relate to other vehicles.

And yes, I hand typed all of this.

Order goes:

Yeah, I'm working through it. I'm 21 years old with what feels like the beginning of arthritis or carpel tunnel. Trying to get done at least half a page at a time.

The list will be finished first thing when I wake up tomorrow. My hands have been hurting/tingling a lot lately... trying to give them a rest.

Is there another thread somewhere on how to read the codes? Are these ODB I vehicles, EEC IV, etc? I have a few code readers.

Oh man, I can't thank you enough for your effort here, I just pulled 9 codes using the wire trick and started to wonder what they're about. Now I can communicate better with my beastie.
