Release Notes
 
A Cisco 12016 router with Standard AC-Input Power Subsystem
containing three (3) power supplies may display the following
symptoms:

1. The output of "show environment power" may show a voltage and
current reading for PEM4 even though there is no forth power supply.

2. ENV_MON-2-VOLTAGE messages may be seen indicating an abnormal
voltage reading.

This is a cosmetic problem.

There currently is no workaround.

I have searched and found this Bug related to 7513s.

It seems like 12.0.22 S* version has some problem.
Isn't it - 12.0.22(S1) - deffered by Cisco?

If I were you, I will try to load different IOS.
With replacement of whole chassis, that will cause some issue.
We had same recommendation with different issue.
It turned out that there was software bug issue regarding
virtual-template.
We are waiting for bug-fixed release at this moment.
