SR20 MAF part number(s)

[onsight512]

Are there more than one pn that'll work for an SR20? My car (S14) has a MAF with pn 22680 53 01.
I think the correct one should be pn 22680 52F01. Does anyone know if these two are interchangable?

There often are 2 different FI ECUs on the same car which may take 2 mas meters
My suggestion is to have the vin of the donor car and see nissan parts .
not possitive about pre obd2 cars , but they send 1 or 2 communications of data before sending the needed data bundle , if it doesnt recognize it it may go to a fail safe system processor ( which runs richer, but the main is 10x the size of the FS , and the FS not built to have that much use)

Ah, thanks. Considering the car was running properly at one point most likely means that it has the correct MAF (pn) on it. I'll replace it with the same MAF pn (once I manage to find one!).

I bought the car in its already-swapped state, so I've no idea on the donor car's VIN. Thanks very much for the information.
