MAF sensor output voltage?

My OBD reader is showing the MAF sensor is reporting 0.00 lbs/min no matter how much air is passing through it. I checked the output from the MAF sensor wire (yellow) with my multimeter, and it shows about 3.50v WOT and 4.85v when idling. Are these normal voltages?

I'm thinking my OBD reader just doesn't know how to read the MAF output from the Intrigue, but I just want to be sure.

Nevermind. Turns out it was my scanner. I updated its firmware and all is good.
