I have 2012 Nissan Versa Sedan that I have had from new. All of a sudden the passenger door front does not open with remote but opens manually from inside; passenger door rear does not open with remote and does not open at all - it is locked and cannot open manually either. Both driver side doors open as normal with the remote. Is there a specific fuse that operates both passenger side doors? If not a fuse, what would cause both passenger doors to not work but both drivers side operate normally?

Yikes, that's scary. Welcome to NICO.
I've never heard of your problem before, but I agree, it sounds like either there's a fuse or a wire got disconnected somewhere.
If you're willing to do some digging, you can look in the factory service manual to see how it all works.

Thanks for the detailed service manual

It's also possible that the battery for your remote might be beginning to fail. That's an easy and free check.
