Temperature sensor Help please (was 5KCSTQ Cold Start

[Ti Kan]

Peter,

The temperature sensor in question is the one for the ECU, not for the
radiator fan.  It's not a thermo "switch", but rather should have a
resistance curve that varies with temperature.

I think the sensor should only have one electrical contact on it, but
the one that Louis describes has two terminals, which leads me to believe
that he is looking at the wrong unit.
