Thread: difference between MAF's

As most of you know the 02-03 spec v's have to use the same MAF and the 04-06 has to use the same MAF, but..... you can also use the altima MAF of the same years. you can also use the 2000-2006 sentra MAF's on your qr25 but not sure if it will have the same scaling but it's a straight in plug in with the same pinouts. In the part bin theory it says it should be the same thing.

As of now the known facts of the MAF's are...

SER/specv 02-03 is compatable with the 02-03 Altima

SER/specv 04-06 is compatable with the 04-06 Altima

B15 MAF
White=12V
Red=Not Used
Green=0-5V signal
Black=Ground

Wait im konfused... "you can also use the 2000-2006 sentra MAF's on your qr25" ??

in theory speaking, yes. but it might scale the air/fuel differently bit it has shown that its the same.

oh you mean qg mafs?

Jamil, are the part numbers for all the sentra and 2.5 Altima MAF's the same ?


Thread moved to appropriate section, this doesn't belong in Electronics.

i'm not sure if it's the same part number

but it's compatable

it wouldnt matter as long as it has the same pins as ur plugg... ur ecu reads and determins how much air is goin through,and adjusts fuel amount, not the maf... it solely monitors air amount and temp and alll that.... and yes, altimas have same motor... as long as its the same motor, mafs will be compatible...my bros altima maf fits my car...
