Hi

Can anyone advise where I can find the Maf Sensor on a MY01 WRX, need to test it as might be on the blink, just want to make sure I'm unplugging the correct thing

Cheers

 

It's the little thing on the right hand side of the airbox plugged into the inlet tract by 2 locking torx screws. If you can't find it by yourself though I'm a little unsure on how you intend to test it.

Thought it was that. I thought you could unplug it to see if the car struggled, from what I read I thought if it did not affect the engine it was kaput?? Can this be done on the MY01 I presume it's the same principal?? Can anyone confirm

 

did you get anywhere with this?,i've just purchesed a my01 and even though the clutch is slipping sometimes a bit and could be the problem,is that when excellerating,the turbo seems to kick in between 3-4000 rpm quite aggressive and pulls all the way up to redline which i like,but sometimes it doesn't,it seems a bit flat and then at say 5000 rpm it picks up a bit but nowhere near as aggressive as when it kicks in early,it runs fine on tickover and doesn't run lumpy so was wondering if this was a likely dodgy maf??

 

If you unplug it, it will be recognised as a fault straight away. And the the car will drive like s****, not recomended. I previously had 3 MAF's go with no such warning.... Then again mine's an MY99 which is renound for it's MAF eating capability.

I think, without measuring MAF voltages the only real way to tell is to replace it completely and reset the ECU.

Personally if I still had one I'd change it every oil change, or at least every year.
