Nytro air pressure sensor voltage check

[canucklehead]

Trying to troubleshoot a couple of nytros we are having issues with. I found the voltage check procedure for an apex and it says we should get 4.75-5.25 volts dc. We did the test on the nytros and we get about 3.25-3.28 volts. Is this what it is supposed to be for nytros?

Thanks
