If you haven't already looked under the IM temp sensor's rubber boot, 
then do so in order to verify that there are good electrical 
connections. I believe the factory connectors are welded/crimped, but 
if there's been a previous effort to fix or replace the sensor, you 
might find a badly soldered connection (that's what I found on one of 
my cars--but even worse, there was a stray strand of wire shorting 
across the sensor terminals).
