Roman coin legend

ColinCMR

What does the P and F stand for in the following legend:

IMP CARUS P F AVG

My guesses are:
P = pontifex
F = some personified word, like fides or fortuna

This will be the first Roman coin I've ever fully attributed, thanks for any help!

And another thing, did Carus really die from a lightning strike??

Have a look at the ARTICLE I WROTE ON THAT SUBJECT.

Great article, Dead King! Deciphering the legends on Roman coins is great fun.
