You have probably already checked but it's an easy mistake. I cleaned my MAF and had no power after wards. Was stumped for a few min then realised I hadn't re plugged it in

My bad, wasn't thinking, "clunk"

Thank you YNOT! I have a problem, I could not find the sensor cleaner in the market over here... I live in Bolivia. Would you know of anyother "cleaner" that would do the job?

Hi all, Does anybody have some idiot proof instructions and advice for me on how to clean the MAF on a 1999 2.8.
Is it the same thing a the 3.0 info that YNOT kindly posted in this thread or something different ?
Please excuse ignorance - just learning, and thanks in advance for any info !

well i went out today to see if the MAF sensor was dirty or not
i installed the provent 200 catch can just before xmas ive drained a bit of oil of
a couple of times and thought id take a gander well well dry and clean as a new borns bum
it certianly works for me

HI Tony I have a 2005 gu with a ZD30 motor the maf part no is 22680 7S000, However the wire codes are different to those quoted by you , mine are looking from the front of the vehicle left to right

Can you give me the voltages /details tks and rgds teago

Theres a 4 pin and 5 pin, I'll get you a part number for 5 pin $115 on fleabay


back again like magic, pt no on box is 22680-AD21A

Tks very much threedogs Cheers Teago

What if the red wire voltage reading is 13.8v?
That's what mine does. White is on 12 V which is the same as the battery voltage

Thought I had a MAF problem & acquired an engine management booklet. Free. Goodee.
Wiring diagram didnt show GU IV & then i realised YNOT had the colors worked out. Thank YNOT. Thought I was going to buy a MAF until I sorted the wires & colors out. Nissan want an exceptional quantity of $$$.
