Before doing any of this, if you have a three prong connector. Get the car to normal operating temp and unplug the sensor. If the fan comes on, it is the sensor.
When I hook it to the voltmeter on 200 K ohms the numbers jump up for a split second then it reads 0.00 tested it several times. What does this mean? I'm not finish your video yet. I'm just excited. I hope it's what I think it is???
Did you figure out the issue? Im having a similar problem with my 1999 oldsmobile 88. Coolant fans not coming on automatically like supposed to but will come on when sensor unplugged
I installed the new sensor since I had in on hand anyway, but as the testing showed, the original one was not faulty. In the end, I had a faulty ignition module, which, on a cold start, would not fire on two of the 6 cylinders. So it ran pretty rough on a cold start. But after a few minutes of warming it, it would resolve itself and run fine. So we replaced the ignition module, and now all is well. Your issue sounds completely different.....Good luck.
That's strange... Maybe the car has more than one sensor. I did see a similar problem once, the guy used Teflon tape or thread sealer and the body of the sensor was isolated from the ground.

Thanks for the video. Now I know how to test my temp sensor!
Thank you.
Thanks to your chart, i found my answer, thanks !!!
Very nice. Where did you get the printout with the specifications from?
do you know hold the wires on the leads like that you are measuring your body resistance in parallel
Anyone know the temperature readings range different between a probe and on bolted to the head of an engine instead of submerged probe?
