Hi all

There is a strong possibility that the MAF sensor on my 99 version 5 sti is faulty and I was wondering what sort of price I could expect to pay at a main dealer.

Been told it will take an hour and a half to do a diagnostic to find out whats at fault before I know for certain.

Before you say it yes I should have asked for a quote for labour

Just lookin for an idea of cost

Would be easier/cheaper just to buy a new one - give Alyn at AS Performance a ring. IIRC about £100 delivered if not a bit less. Can fit it yourslef in a few minutes....

Or try Keith at Scoobyprojects (sourced through Nick & Cath at Advanced Automotive):

Cheers mate thats by far the cheapest place ive seen.

Once fitted what do i have to do. Doesnt it need 'rescaled'

Just refit, disconnect the battery for half an hour to reset the ecu and clear any fault codes, then connect battery back up and away you go

Gotta love main stealer quotes..... The hour and a half diagnostic will consist of nothing more than connecting the two black connectors under the steering wheel and then reading the fault codes off the CEL - something else you could do yourself in minutes. There will be plenty of guides on here as well as a 'key' as to what the sequences of CEL flashes mean (they come out like morse code).

Once new one is fitted, read the ECU codes using the black connectors again to ensure you get the 'all clear' signal, as shown in the link above.

Job done, wonga saved...

hi there just did the ECU code things with the black connectors and I appear to have a score of 44 if i understand it right indictating a "turbo charging pressure control signal"

bare with me on this one troops it was my first time

If a dash = 10 and a dot equals 1

Its flashed dash dash dash dash dot dot dot dot - 1.8sec pause. = 44 if im right

If it was the MAF it would have been dash dash dot dot dot - 1.8 sec pause = 23

What causes the 44 fault code for turbo charging pressure control signal? a split hose

ginger321

forgot to ask as well does it just keep flashing continually repeating itself.

Kept giving a reading of 44.

yes it will continually flash the code/codes untill you re-set the ecu

Could've been an old code.

A faulty maf won't neccessarily throw up an error code either.....

ginger321

shall i reset the ECU and see if it goes away if its an old code.

Yep, start with that and see what you get. Just disconnect the battery for at least half an hour.
