as far as i know the temp I sensor is the intake air sensor in the afm.
do you mean the coolant temp sensor that send the signal to the coolant
temp gage in the instrument cluster?  if thats what you are talking about
its a resister that varies the resistance to ground with temperature.  if
you ground the lead to the sender the gauge should go all the way to hot.
