2002 LeSabre DIC/Temp Gauge Sender Location
 

With the 2 wire cable connector Disconnected from the ECT/computer sensor, from a cold start I can watch the DIC and temperature gauge readings rise to 170~190 and sometimes 210.
The dealers drawings say the ECT sensor is used. Located under the thermostat. There must be another sensor, but where is it.
Any thoughts appreciated.
