2007 Yukon XL pressure gauge reads zero

[Farmingdales Finest]

Last night I saw my pressure gauge reading zero but the idiot light that would indicate that pressure was low did not come one.

I also did not notice anything else out of the norm, It rode normally and the engine temp was normal,

Is it safe to drive?! Is it just the gauge broken or possibly a fuse?

Pressure sensor or wiring would be my guess

I've got a 2004 Tahoe. Recently my speedo began acting erratically, showing 120mph when doing maybe 30. I read a lot of suggestions suggesting a swap-out of the individual units (speedo/oil/temp/etc) located immediately behind the faceplate. However, I pulled the fuse, turned ignition on/off, waitd a few minutes, replaced the fuse, and the speedo has been correct ever since.

I've had lots of little issues and they all seem to have begun following the battery replacement. Just saying.......
