2002 LeSabre Temp Gauge Sender Location
I disconnected the yellow and black wires from the ECT sensor below the thermostat. (ECT varies from 6.14K ohms @ 60*F to 360 ohms @ 130*F etc).
With ECT Disconnected;
Started engine from cold. Both fans come on full. I can watch the IPC DIC readout and Temp Gauge rise to around normal readings.
(but take an abnormally long time to reach normal and tend to vary somewhat which is what got me started on this). Repaced the thermostat with a 192*F unit. Same operation. Which makes me wonder if the ECT sensor is OK and there is a second sender.
The schematics I have and the dealer's technician's and parts computer schematics show only the ECT sensor ??? I hope to replace the upper intake manifold in the Spring and will do a thorough search then but would like to figure this out sooner.
Any help appreciated.
cheers, dave dbm8@shaw.ca
