code p0117 on a 3800 on 1998 Oldsmobile Intrigue

i am getting a code p0117 and my temp gauge is all over the place right from start up, i replace the temp sensor and did not see any bad wires leading to it and still having the same problem. also the fans are coming on right away like the engine is hot even after sitting in 30 degree temps overnight. could it be the dash panel itself is bad? i have heard that could be my problem ... any ideas?
