Lexus RX hybrid IAT sensor issue

I own a 2022 Lexus RX hybrid with 83949 km. My check engine light came on. I've noticed reduced engine power and rough running. The diagnostic tool shows a fault related to the intake air temperature. Could a defective IAT sensor be the problem?

I had a similar issue with my RX. Did you check the temperature reading from the IAT sensor using your diagnostic tool? What values are you seeing?

Yes, the temperature reading seems unusually low, even after the engine has warmed up. Could you elaborate on your experience and confirm if your symptoms were identical?

That's exactly what I saw - consistently low temp readings. It does sound like the IAT sensor. I ended up replacing it. I'd suggest getting it checked at a workshop.

Thanks. I will have it checked by a professional. It seems likely to be the IAT sensor. The repair cost was 155€, including the sensor and labor. Your input was very helpful.
