Temp guage stopped working...kinda

OK, my temp guage is going freaky on me. Some days it works, others it only moves up to about the first line and stays there. No rhyme or reason I can see as to when it works and when it doesnt. The car seems to be still running at a normal temperature, never had any kind of overheating issues out of it ever, and the heat still works great etc... ideas?

What year?

What engine?

sorry, forgot to mention the important stuff. :screwy:

it's an 01 w/ the v6 just shy of 200k miles on it.

check ect sensor wiring and connector for tight connection or damage, if wires are all good replace ect sensor.

how is the coolant level?

Thanks guys, I'll check the coolant lvl, althoug when I checked a few weeks ago (I was already having this issue) the lvl was fine. I haven't had any issues with losing coolant since I had to replace my intake gasket 125k miles ago (damn that orange crap) I'll check the wiring as well.

It is possible that there is a ground issue with the temperature sensor? Or it could be the temperature sensor.
