I had the same problem on saturday.
I'm using the factory sensor (different engine though). Its been fine up till now.
And what it was doing was going hot-warm-normal-hot-warm-normal-etc.
Even coasting along idling. Then even coasting along with the engine OFF. hot-warm-normal ...
I think I've got another water temperature sensor somewhere. I'll try that.
Thug: Have you got a spare sensor you could swap and try?
Sideshow: The plug on the sensor, how well does that need to be on? My plug is a 1 wire connector and it kinda sits on, but can be wobbled by hand.

i had the same problem on saturday, i think that the 1g should be able to handle heat better than a 2t, so im thinking the guage in the celica is more senceitive than that of the supra
ao when its reading half its realy not half, but lower
hows the theory sound?

i'd seriously think about getting a seperate gauge, even if just to check what is going on..... you can get pretty cheap remote sensor ones... even VDO on ebay for $45 + 10 for sensor i think... Pricols are even cheaper and almost as good... when you start mixing and matching sender/gauge, hard to tell what going on..
also if there is any crud on the sender surface insulating it from the temp, or crud on the threads (since it gorunds thru the thread to the block), it may have probs... might be worth pulling the sesnor out, cleaning it and the hole, and whacking it back in....
has to be a bad earth  LOL

OR... is your fluid level in the engine OK? if the sensor sees steam, it will climb off the gauge.
Steaming sensor will also leave coating of corrosion/crap on sensor and will affect temp readings.
whats fluid level level like in radiator?
can you take sensor out and put business in a cup (one of insulated coffee mugs) of fresh boiling water and see if gauge reads around the normal mark?
if you're really worried, drive very sedately and rotate radiator cap so it's loose (holds no pressure, stops water splashing everywhere, keeps temp to about 100C) until you get a new sensor (or pinch one from the wreckers).
