Talento outside temperature sensor fault

My 2020 Fiat Talento with a gasoline engine is throwing a weird error. The outside temperature sensor seems to be faulty. I'm getting an error code, the AC won't kick on, the spray nozzles are frozen even when it's not that cold, and the mirror heating is dead. Any ideas? I'm guessing it's something simple like a bad connection?

A 2020 Fiat Talento is experiencing issues with the outside temperature sensor, leading to an error code, non-functional AC, frozen spray nozzles, and non-working mirror heating. The likely cause is suspected to be a bad connection, such as a loose or corroded connector. After checking the plug and consulting a mechanic, it was confirmed that a corroded connector was the issue, which was resolved by cleaning, restoring all functions to normal.

Sounds like a real headache! The fact that multiple systems are affected does point to a common cause, like you said, a bad connection. Have you checked the sensor's wiring and plug? Sometimes a loose or corroded connection can cause all sorts of gremlins. Where is that sensor located on your model? Is it in the mirror?

Yeah, that's what I was thinking too. I had a quick look at the plug, but nothing obvious jumped out. I don't know where it is located, do you know where I can find it?

Okay, since you've already checked the plug, it might be worth having a professional take a look. Given the symptoms and your mileage (186963 km is quite something!), it's likely a faulty cable or plug connection, as you suspected. A workshop should be able to diagnose it quickly. In terms of repair cost, I would estimate 95€ to do the job.

Thanks for the advice! I took it to a local mechanic, and you were spot on. Turns out it was a corroded connector. They cleaned it up and now everything's working perfectly. Appreciate the help!
