Yesterday I had to test an automotive EGT (Exhaust Gas Temperature) sensor. Every time I had to test such a sensor it was an RTD type or a Thermocouple.
In this case it was a ~150k NTC thermistor. It was behaving as an NTC to be more exact. Negative coefficient and sensitive. The temperatures in the exhaust are almost 1000 °C.
Later I confirmed it is a thermistor.

I was under the impression that an NTC can;t go that high without being damaged. Is it a special type of thermistor?
