Another way to easily confirm it is the sensor (especially if you have spare resistors lying around), is to check what the cold resistance value should be and insert matching resistor(s) into the pulled connector-plug. A quick check of the FAQs gives the following resistances - but not sure if they apply to your sensor or not.

32F (0C)-- about 6000 ohms within a range of +/- 10%
68F(20C) -- about 2300 ohms
104F(40C) -- about 1300 ohms
140F(60C) -- about 600 ohms
176F(80C) -- about 300 ohms
212F -- about 190 ohms

Check the wiring diagrams to figure out whether you have a single or dual-thermister ECT sensor - which would determine whether you need to use 1 or 2 resistors respectively.
