Avensis outside temperature sensor problems

Interesting. I own an Avensis too, and this sounds familiar. The AC and mirror heating issues especially ring a bell. Did the diagnostics point to the temperature sensor as the only problem?

Yes, the diagnostics said it's the temperature sensor. But can one sensor failure really cause so many different problems? Could a faulty temp sensor actually disable the AC compressor and the mirror heating?

In my case, the sensor was the problem. The ambient temperature reading affects several systems. It seems like a stretch, but replacing the sensor fixed it. The shop said this type of sensor malfunction isn't rare. Maybe talk to a technician?

Thanks for the advice. Taking it to a shop was the right move. Turns out the diagnostic was correct: the cable or plug connection to the sensor was faulty. Cost 95€ to repair. Thanks for confirming my suspicions.
