Read a ton last night trying to educate myself.

One video suggested you could test the sensor by using heat and checking for continuity. So I took the old sensor, used my tester between two of the three prongs and when cold it read1 (on the 20k scale....meaning no continuity). Used my heat gun and warmed it up and it started dropping like a stone after about 1 minutes of warming it up. Eventually it got down to about 98 (from 2000) and using my infrared sensor it was about 220 at its hottest part.

Pulled the "new" sensor out and tested it and it did the same thing.

So...both sensors good and I am chasing my tail? Or the new sensor was bad as well? The symptoms were the same with either sensor.
