94 F250 Code Reader
Seems ever week I have a new problem with my truck. Wanted to asked if a Equus 3145 Ford Digital Code Reader is good enough reader to help determine the codes that are causing the engine light to come on?

the other option is free (depending on your availability of wire laying around). i have a piece of 18 gauge or so about 3 ft. long and i follow the directions on the fordfuelinjection.com site to pull KOER & KOEO codes. after doing it a few times, it becomes a fairly easy procedure to get the info you need. just a suggestion, but if you've got the $$$ to purchase, by all means do it!

I'm thinking about grabbing one as well. For $25, why not? I've always used the wire-from-diag-port-to-ground-and-count-the-flashes method but I usually have to do it several times because I'm never confident that I read the codes correctly.

Received code reader, hock it up and did self test key on engine off. Got the code 111 then 10 then trouble codes 126 the 334. Can anyone lead me to the cause of these errors. I think 334 referred to EGR Valve, I replaced that about three weeks ago.

The problem was last week it started running rough and shifting hard when the check engine light came on after starting it then when light went off after a mile or so it went back to running normal. Later in the week the light keep staying on longer and finally all the time. After I ran the test today drove it a while, no engine light or any problems. I have replaced both the mapp sensor and egr valve recently. Wonder if maybe the old plastic vacuum lines might be the cause.

Did you clear all stored codes when you replaced the EGR valve three weeks ago ???

Well, that would work.
A better option, and much easier, would be to thoroughly read the manual that comes with the reader.
It gives directions on how to erase the stored codes.
Erasing stored codes via the code reader vs. disconnecting the battery will avoid the process of the PCM having to re-learn itself.
I know, it's a guy thing, instruction manuals were meant to throw away or hide...........never be seen again.
