Corolla 4AGE thermal fan sensor

Hi Guys,
I have a question about the thermal sensor in my 89 SX Seca (4AGE). I got the car in winter, and have been trying to systematically get to know its ins and outs etc etc (last weeks effort was the squeling brakes that led to replacing undersize rotors and pads!). From memory of our old 92 Camary, the electric fans used to be on quite a lot, yet the fans in my Seca have never come on.
It finally got warm in Canberra this weekend, and i expected the fans to come on, but nope! I pulled the plug to the thermal sensor, and the fans both came on no probs.
Does the 4AGE just run 'cool' then? My temp guage never goes above its 'normal' position (ie horizontal) which seems to be where the thermostat opens. What is a safe way to check the sensor is working correctly, and at what temp should the relay open?
Cheers Chris.

pull it out plug it in and wave a lighter under it to heat it see if the fans come on, dont go over the top and cook it tho!

I find it hard to believe the fan only comes on when the engine is idling. Ha Ha Ha you guys crack me up.
