Just incase anyone gets ripped off like I nearly did by my local dealer trying to get a MAF sensor only (£76 inc) instead for being charged £280 for the complete thing.

The part number is 22794AA010 - Meter CP-AIR Flow

Made me mad, just want others to be aware that this part IS available as the sensor only.

Thanks to Cheam Motors for supplying the part so quickly. :)
Thanks also to the late great Moles Dad who I know found this out :D
John

Has it fixed your problem..???

Dan

:) Yup! :D

nice one..!!!!

Dan:D

mega-stream

nice one mate :)

Dealer tried to sell me the whole unit a while ago as well. That was on the first occasion the MAF went :rolleyes:, got a bit wiser since then though.

Cheers for the part number

Think I'll buy a bulk load ready for the next time/times :rolleyes:

MS, any idea what caused yours to go? Don't want to start a "this induction kit does and the other doesn't" debate, just curious if you think it was induction kit related.

Cheers

My car is 100% standard, standard air filter and induction, standard everything.
They just go, one went on MY99 car after 22k miles, that too was standard, this one went on my Sti Type RA after it doing just 5.5k miles.

Proof that its got nothing to do with induction kits maybe?
Emm, now there's something to think about :D

Its a weird part though, I was expecting a fragile piece of wire element, but this is hard resign type plastic with a kinda ceramic bit on that does the sensing, tuff as nails to look at.

Bizarre! Thanks for letting me know, I've only gone thru' one so far on my 99 - with nothing std:D

Mega_Stream, useful info. :)

would you know if this is the same part for STi5/P1 by any chance?

Steve.

mega_streams car is an STi5 so it should be the same..!!

Dan

Many thanks Dan, I'm was thinking of keeping a spare!!! :D

Steve.

Grrreuch! Just paid £119 + VAT at Graham Goode, but I guess they did fit it for free. The newer ones are more reliable than the older ones it seems, so I did it just in case...

What part did GG fit?, I was told that they would have to import the part as it wasn't a standard UK part :confused:

However checking all the associated parts against my old MY99 UK car, they ALL had the same part numbers on. :D

There wasn't much discussion Mega - just a new MAF sensor. I would doubt there is any difference between models - the ECU copes with different flow rates after the MAF simply reports it?

Hi,

Is this the same for the my00 nov 99 car.

Thanks Paul

Yes. All MY99s and MY00s use the same MAF, so the part number is the same too.

Cheers,

Wrexy.

Same part number for the JDM spec MY99 and 00's as well both STi and WRX !!!

Is it the same for the '02 STI?

Thanks guys,will get one ordered,do you know if this is the same part,i know its a different no,is that simply because of the usa code. http://www.subaruparts.com/cart/?pn=...=13&submit.y=4 at this price i might get a few in.

Cheers Paul

Checked with dealer today and the usa one is the same as the uk but for na only.

Andy,

Not the same for the 02' STI. It uses a different MAF altogether.

Cheers,

Wrexy.

do thay fit MY98 scoobys

cheers

What are the symptoms of a failing or failed MAF (other than psiton meltdown) on an MY99/00 ?

Scott T

Irregular idle (often as bad as hunting from as low as 200rpm to 900rpm) is the main symptom :(

Cheers

DJ,

No they don't.

Cheers,

Wrexy.

£76 for a maf sensor!
here is holland the are 35euro =£25

better get yourself a few and advertise;)

Other than hunting and idling problems, what other symptoms does a failed MAF have? Any reasonably detailed descriptions of where in range and what the symptoms were from personal experience would be good...?

I have a standard MY99 which has had melted pistons on 3 ocassions..am rolling roading it this week, but would be interesting to know...

Thanks.

There is another symptom that is evident and that is where the ECU puts the car in limp home mode due to a failing MAF, so you get bugger all boost and I think you can't go over 3000 rpm.

Then there is the killer symptom where you can't tell that a symptom exists. It is where the MAF starts to under read making your ECU give less fuel, resulting in a lean mixture which leads to melting the pistons. This is the bad and worst case. Your car will feel like it's getting quicker due to the leaner mixture, but few would know or be able to tell that it is a failing MAF causing this.

This may have been your problem. If you haven't changed the MAF get it checked with EcuTek Delta Dash. Do a run at WOT, in say third gear, to about 6800rpm and check your O2 sensor readings. If your car is a stocker then you should be seeing over 0.91 volts. If you have under 0.87 and it's a stocker you have a problem cos the O2 sensor readings are never that low on a stock car. If you have under 0.90 volts the MAF could be on it's way and regular checking will be needed to see if the readings keep dropping to catch the situation. I'm not sure if a Subaru select monitor can check the MAF on a run like you can with Delta Dash.

Cheers,

Wrexy.
