I am desperately searching for a wiring diagram or a I/O vs Signallist for one of my experimental MAF sensors that is waiting to be installed....
Thoose are for my test to install a MAF sensor from the Acura RDX 2012 on another car(Sorry not a Honda a Volvo 9 series estate sleeper with a EFR turbo)...
I suspect this sensor are of the same hardware functionalities and therefore use the same MAF transfer curve caracteristics as the MAF 0012 Mustang and MAF 0031 used on Nissan GT-R..
This one used by Honda fits physically better in my airfilter box than the other upright types....

Type of sensor Hitachi "slot type of sensor" :
MAF 0033 or AFH70M-41C or 37980-RNA-A01

This is what I have found so far but I am not sure about this...

PINOUT
1. Signal ground for sensors PCM/ECM IAT ?
2. IAT sensor output
3. VGM Verified Gross Negative signal = MAF Signal ground PCM/ECM
4. VGP verified gross Positive signal = MAF signal reading to PCM/ECM
5. Fuse under dashboard IGnition = +12v ?

Is this correct..
Does anyone know were to find a product description or any information in how to setup this sensor...

 

Your pinout is correct.

These are the stock AFM flow tables from Ktuner for the MAF sensor you are using.

Hope that helps a bit.

 

Thank you so very much I have been searching for the maf transfer curve and the wiring setup for a while over the net...
This will be interesting since what I have been reading a 0-6 volt sensor and my ECU are supposedly to be able to read appr. 0-6 volt...
So I dont have to use a resistor or buy a HPX-E sensor to take advantage of the sensors wide range...

My humble thanks

 

Hi again is the MAF sensor situated in a 2,5 2,75 or 3 inch tubing on the Honda Acura RDX....
Or I should maybe put that question as a separat question on the board..
Thanks a lot once again...

 

The stock MAF housing is a 3.25" inside diameter.
