Title: Code reading, 95. 2-9.
Post by ro284 on Nov 21^st, 2013, 8:52pm

The main reason is that after rebuilding engine, and rewiring, etc. I want to check for anything that might cause a problem for MOT, I have made an led reader to read the EEC 1V, First i cleared out any old codes, As there must have been a few after the engine packed up! The first code is in KOEO mode is 76, == Vane Air Flow (VAF) did not respond to "goose" test, can anyone enlighten me on what this is Please? I have tried the KOER test, but the led is too bright! And i could not see properly for a while! So will tone that down a bit to do the next test (engine running) There are a couple of codes, difficult to identify at the moment, but that’s the next thing, as it takes some getting used to! As a matter of interest, my volt meter display cannot change quickly enough to read accurately,
Any advice Please Bob

If you look here:
http://fordpartauto.com/vane_airflow_sensors.html

It says “Ford's trouble codes that apply to the VAF include: Code 26 indicates a VAF reading out of range, Code 56 indicates sensor input too high, code 66 is sensor input too low, and code 76 indicates no sensor change during goose test.”

Can’t claim to know anything about obd on the 12v but presumably if the engine is not running you wouldn’t expect the reading to change on an airflow sensor.

Thanks Tompion, a usefull link there, and no you wouldn't expect any change with engine off :)

I have a lot of the CODES from the EEV1V on a PDF I will put them on a link for you .

HERE THEY ARE (http://sdrv.ms/1fpLNG9)

I haven't a clue on this, so just guessing.

Snoopy’s list gives it as no change in WOT test, perhaps you didn’t get the throttle open bit right in the KOEO test.
It seems strange you should get a code for this unless the value should change, I’ve never seen mention of a VAF before I assume the 12v has one?
If it does have one & is some sort of flap I wonder if it should get moved at wide open throttle.

With regard the volt meter I think you need one with a needle not a digital one.

I think you said before you had problems with tickover, assuming you have a VAF this may be of use:

Many thanks Snoopy, for all the info, much appreciated, Thanks Tompion, i may have got the full throttle test wrong, but tried this twice, i am used to the led now having sleeved it! i should not trigger a migrain again!
I have had a VAF on a car, not sure which one, but unless i have missed the obvious i don't think there is one on the 2-9, code 76 was the only one i found in KOEO, I did have problems with idle, but with new plugs (correctly gapped) the tickover is very good now, the best it has been, i expected the adjuster to be correctly set after rebuild, as it was, but had to wind the adjuster in one turn to get there. (having removed tamper proof cap) so code 76 bit of a mystery! Thanks again guys, i'll see what KOEO, shows up, Bob

The tick over and timing can only be adjusted when in " maintenance mode" any attempt to adjust any other way will result in the EEC trying to set it back to where it was.

Thanks for that Snoopy, Something else i never heard of!" maintenance mode" is there any info on this please? It sounds like i'm going about this in the wrong way, trying to learn some things as i go :-[ So it would appear that if i can get to, or if i need to " maintenance mode" i will lose any settings and have to start again? I'm beginning to think i should have scrapped the car when the gaskets went. I will Donate again when i have finnished and got m.o.t. paid for.cheers

Have a look here:

Assuming it's the same it goes into service mode after you fully depress and release the throttle at the appropriate point.

Thanks again for all links, Tompion, They are a big help. i will get it sorted tomorrow. cheers Bob

I have put the Gunson User Guide on my sky drive for all to access. It is with the EEC1V Codes

Just an update, not on the codes, on the car, i drove it a few miles yesterday, very nice smooth ride, responsive engine, reliable tickover, great, (not done codes yet) This morning i noticed a puddle, and the Rad plastic end appears cracked above the fan sensor,and leaking the new Antifreeze i put in last week! does it ever end! The only thing i can do i guess, is book it in for mot, and see if anything else shows up! :-/ 95 rad anyone? Bob

Bob,your rad is peculiar to the 12v engine having the fan sensor in the offside tank.
Sounds to me that once you have done the rad you should forget all about trying to extract codes,as the Yanks would say "if it ain't broke don' fix it".
I would have a go at repairing the tank first,Baz's Dad swore by MILLIPUT to repair just about anything,and on his recommendation I have used it to good effect on numerous repair jobs,if you drain your coolant to below the crack,give it a good roughing up and apply the unction leaving overnight to harden,the stuff can actually be used under water 8)

Yes thanks Gozz, That sensor does not work anyway, i am waiting for a Kenlowe temperature controller to come along to drive the fans, but after all iv'e done i have this problem, tempting to give up at the moment!Are these rads repariable do you know? Thanks Bob

Bob, if it helps there is a firm near me (http://www.sylmasta.com/acatalog/index.htm)who do the stuff and some others as well. Look at the superfast putty link. I used the Titanium one for a leak on my rad ages ago and it seems to have done the trick. :)
