He said connect to an ohmeter, should read a steady 850-1200 ohms. using an air heat gun, start warming the sensor
Well I took mine out again and tested it. Temp. in garage was 75 degrees F.
At that temp. CPS showed 1113 ohms and it held steady at that temp.

When I applied some heat, not to much though ohm reading increased. I stopped when it read 1200 ohms since I did not want to put on to much heat. I did not measure temp. when it read 1200 ohm. I think it's normal for resistance to increase as the temperature increases.

I'd be interested to know how many ohms a new CPS will show.
