Twin cam 16v temperature gauge

I was warming up my car when I gave it a little bit of gas the temp gauge shot down. Then it went back and forth, now it won't move from the Cold side what should I do? Also I hear a ticking noise coming from the intake? The car still turns on and sounds find any feed back will be nice thanks.

check the connection to the sensor. the wire gets brittle over time.
