MAF Signal voltage?

ive looked all over and cannot find or confirm what the sr20det MAF signal wire voltage is suppose to be. some people have said 5v or .5v. would anyone be able to confirm what it is suppose to be for me? im currently getting 1.4v on the MAF signal wire for my car when its running. which seemed a little off to me.

~0.8V when warm. 1.4V is to high for idle, get an extra groundwire on it and clean it.

Good luck

Can I get some more feedback on this? Where does it say it needs to be .8v?

Download an FSM for your car and check from there. There should be a range of 'idle' voltage that is acceptable. WOT is 5.12 maximum.
