EOT temp in data viewer showing a - number (U7165)

[U235a4]

I have the latest rev in the predator (u7165) and using the lastest dataviewer. When I view engine oil temp (EOT) it show as a - valued number like -6910.3, why is this? #2Also what is the differance with the two engine coolent temps? And #3 why does in appear the engine oil shown in the predator that is celuis appear to be more of a trans temp and not oil temp. BTW I have the same results on a 2004 , and two 2005's so I know it is not a truck issue.
