Did you reset the ecu after swapping maf sensor?
|
fault code still showing 23
i will check the plug this weekend for water but i have reset ecu several times and it still comes up with fault code 23, just check scoobypedia and when ive been reseting ecu i just plug both black and green plugs together and drive for a few second until check light flashers then turn engine off and it seem to clear, noticed this is a different proceedure to the one on scoobypedia is that why it keeps showing this fault code ?

faulty maff normally revs from= nearly cut out to only about 1200 from experience on idle have you tried idle when maff is unplugged ?? also try diagnostic with maff unplugged |
iv always been told on the 99-00 years not to run the car with the maf unplugged.

Car Started playing up again today, car revs up to 1500 on tickover, checked diaog plugs and code 23 again (maf) is there any chance the idle control valve can cause the maf fault code to keep showing ????? :(

Think i'd be going back to the dealers at this point mate, let them see the brand new MAF they sold you.
If it is a brand new unit then it is not fit for purpose and should be replaced.;) |
