what are the readings supposed to be if it is good when i run a multimeter on it?

ive serched and found nothing

 

Need to brush up em searching sKiLLZ y0....

For the MAF signal wire (white):

Ignition "ON", engine off: 1.0V
Idle (engine fully warmed up): 1.2-1.8V
2,500 rpms: 1.6-2.2V
4,000 rpms: approx 4V with linear increase in rpms from idle

For this info and voltages for all the other wires (ground, power, reference), see here:

Is there any reason to do this check if I don't think I have any problems?

 

No.... but it'll be a nice learning experience.

 

thanks alot
