Lexus CT200h Outside Temperature Sensor Fault

My 2022 Lexus CT200h hybrid is throwing an outside temperature sensor fault at 163358 km. The AC isn't engaging, spray nozzles freeze even when it's slightly cold, and the mirror heating doesn't work. I suspect a defective cable or plug. Has anyone seen this before?

I had something similar with my CT200h, although I haven't checked the error memory. The AC was definitely acting up, and the mirror heating was unreliable. Could be the same thing. Did you check the sensor itself?

I haven't checked the sensor directly yet. I was planning to trace the wiring first, looking for damage or corrosion. Did you fix it yourself, or did you take it somewhere?

I didn't manage to fix it myself. I brought it to a workshop, they checked the sensor. Seems like it was the same problem.

Thanks for the info! It was indeed the sensor connection. Cost me 95€ to get it sorted. Appreciate the help!
