Are you referring to the MAF (Mass Air Flow) sensor?
Customer: replied 5 years ago.
I need to know if the car has a IAT, MAF, or AFM sensor on it. I need to bypass one of these to use a chip. What do I need to look for? What color are the wires? What does it look like, and where the heck is it located?
Expert:  Ron Z. replied 5 years ago.
Ahhh ok. You're installing a Perf Chip. Got it. Usualy those chips are hooked up through the IAT sensor (on some trucks the IAT is built into the Mass Air Flow sensor). Unfortunately,for some odd reason, i cannot find any listing for an IAT or MAF on this truck. Tell you what- let me opt out and i will forward your question to another Tech who has access to more detailed info on older trucks. Sit tight one sec, someone will be right with you. Sorry for the inconvenience...
Customer: replied 5 years ago.

I just need to hear something as soon as possible. Go ahead and open up my question to other mechanics.

Hi,

 

Your engine doesnt come equipped with a maf sensor, iat sensor, or afm sensor.

 

Instead it uses a MAP(manifold absolute pressure) sensor. It is located passenger side, rear engine area, mounted above valve cover end.

You will need to check the directions of your chip to see if it can go into the map sensor. Some can and some are not designed to be compatible with the map sensor.

 

If it is ok, the yellow highlighted terminals to tie it into:

I just was told that it is 1995 Chevy Suburban with the 350, and not a 1994. Does this change anything
Expert:  Eric replied 5 years ago.

Hi,

 

94 and 95 are the same. It will only change if its a 96 model.
