Can someone please adviise mw where exactly I find the MAF sensor on Micra 1.2 K12 (2003) Petrol ?
Thanks
Thanks
It's built into the throttle body, inside the air box on top of the engine....
and as far as I know it can only be changed by changing the throttle body, though can probably be cleaned using an aerosol solvent spray.........
MAP sensor is on top of the airbox, item 2 in the picture below...

and is secured by a single M6 bolt. It can be a little difficult to lift up after the bolt is removed as the 'O' ring around it's body tends to hang onto the hole in the airbox.
They are not cheap, I was lucky in getting a good spare when I bought a replacement airbox on eBay for £15
No worries. Why do you think that you have a problem associated with the MAP sensor? Have you plugged an OBDII reader into the port on the dash, to check for fault codes?Thanks again that is great help
Cheers

My money is on a camshaft sensor fault due to a stretched timing chain. This was very common on the K12's for the first couple of years of production and was finally cured by fitting an uprated timing chain to all engines produced from about early to mid 2005.
Code readers are very cheap on ebay, I got one of THESE for about £10, works great on my K12 Micra, my Saab and my daughter's P12 Primera.
Some info HERE on the problem.....Thanks will get one ! Hmm, I hope you are wrong though .Cheers

no, the diesel one measures boost not vacuumGot one of those bit too quickly ,then realise it says "Disel only" . Hmm wonder if it will work with Petrol ?.
OK thanks.no, the diesel one measures boost not vacuum
It's an OBDII reader, it will work on all cars that are OBDII compatible. The reason that the seller quotes the diesel information is because diesel cars made before the date he quotes are NOT OBDII compatible so he doesn't want any comeback from people buying it for a diesel and it doesn't work. Not sure what Frank's comment is about, it's not a mechanical vacuum gauge??Got one of those bit too quickly ,then realise it says "Disel only" . Hmm wonder if it will work with Petrol ?.

Don't forget, 'ignition ON' engine NOT running.
Well if the garage charged you more than an hour's labour to do the swap they stitched you up......possibly half an hour's work for someone that was really familiar with the K12 but one hour is more realistic if they hadn't done one before.....OK well the garage fitted the (USED) Throttle Body I bought off Ebay for £16 total. (Guess how much Garage charged me to take old one of and fit new one (go on have a guess) ?) NOW the car does NOT cut out randomly as it used (upto 8 times on a 30 mile trip and dangerously as just Cut off,no engine at all ) to BUT still makes the pop pop misfire type sound but runs "ok" (not good but ok) .Unplugged the MAP sensor and the engine ran much more smoothly so have ordered a new MAP sensor.
