At idle from the signal wire off the MAF what should the voltage be?

I know the 03 to 06 ones at idle are about 2.54, is it the same for the 2010 model?

I was getting codes and the vehicle is in limp mode, just trying to rule this out. Replaced the MAF sensor but I think it might be faulty. At idle I get volt readings of 1.84.
Thanks!

Each application will vary slightly due to engine wear and idle speed. What is the voltage with the old sensor? 1.84 volts pretty close to me but if you think this is a problem try and replace the MAF sensor and compare. Check out the images (below). Please let us know what happens.
