Temperatures from 'prtdiag -v' not consistent

I am trying to use output from 'prtdiag -v' on an E450 (Solaris 8
07/01) to script an automated warning system which will send email
alerts when the temps are too high.

I'm just using the output from:

        /usr/platform/`uname -i`/sbin/prtdiag -v | \
                 grep -A 4 "System Temperature"
                 
The temperatures are absolutely stable:

        System Temperatures (Celsius):
        ------------------------------
        AMBIENT 15
        CPU 1 40
        CPU 3 40

except once in a great while the Ambient temperature is reported
as 70 (ALWAYS 70, and in my testing approx once per 456 runs).

Any ideas? Is it not a good idea to trust prtdiag's output for
this kind of alert?
