CEL question
I've been driving my plow truck some and doing some work on it getting it ready for snow.
Truck is a 1994 F-250 5.8L auto trans with OD, 8600gvwr part time 4W drive.
The CEL came on so I used a jumper (yea I need a reader for it) to have it flash the light at me and I get
KOEO, 6 2 6 6 2 6= I'm thinking that would be 626 then 626 repeat?
Not showing anything in my haynes for 62 / 66 / 26.
KOEO, (continuos memory) 1 7 2 1 7 2= again a 172 then a 172 repeat?
Its not showing anything in my haynes for 172 or 17 / 21 / 72, shows 72 in the book but thats under KOER test results that I get no codes.
KOER, no code given.
Are those valid codes? The Haynes manual doesn't give anything for those codes. Does anyone have a better book that can tell me what they are for or know of a site that gives all the codes so I can look it up myself?
Truck gets close to 13mpg and seams to run just fine, not effected by whatever is triggering the CEL. I would still like to correct the problem.
Thanks, Dan

yup they're repeats
626: coas clutch solenoid circuit failiure (E4OD)
172: HEGO shows system lean (I had to replace O2 sensor on mine to solve this code) You might want to test your O2 sensor

Ok great thanks,
I know the 02 sensor is pretty old so I'll check it out, probably just needs a new one.
Now for the trans code, now that I think of it it's a reman "jasper" with probably somewhere around 10-15k on it, any idea what that problem is?
I just did a fluid/filter change on it, could that have something to do with it throwing a code? Worked alright but didn't jump into gear fast enough when going from park to drive, changing the filter/fluid fixed that and now it "jumps" like it should right when the lever hits drive.

Whoops I was looking at the wrong section... Strange, this is what my repair manual says under Oxygen Sensor Testing:
http://arrc.epnet.com/autoapp/8828/8828R04_TESTIN1.htm
Then it says this under HEATED Oxygen Sensor Testing:
http://arrc.epnet.com/autoapp/8828/8828R04_TESTIN2.htm
Wierd... I was under the impression that we only had 1 type of o2 sensor in these trucks, a HEGO sensor.

Yea I think I read in the book a way to test the sensor but like you I'll just buy it a new one. Never replaced it on that truck as long as I've owned it.
I don't replace them every 30k or whatever, I replace them when the computer says it's not working! lol

But those two codes came back again.

Well I googled the coast clutch and it looks like fluid type can cause it.
I guess the first thing is I'll drain it all again and make sure its full of Dexron III/Mercon, I may have filled it with type F.
To used to the old ways.....

Ahh wait, don't the newer trucks have HEGO's and the old ones have reg o2 sensors?
