AIT Sensor Reading Negative on PFC

[ZGN]

How many other people have seen this. Is this common for the AIT sensor to fail and read negative?

sometimes mine shows -40 and then it creeps back up to normal.

Yes they can go bad. I have seen it happen several times. There is a resistance test in the manual.

page 358 of the manual:

@ 20c (68f) the resistance should be: 2.2 - 2.7 kOhms
@ 80c (176f) the resistance should be: 0.29 - 0.35 kOhms
