V70 Outside Temperature Sensor Issue

My 2011 Volvo V70 diesel is reporting an outside temperature sensor error at 222109 km. The error is stored, the AC doesn't engage, spray nozzles seem frozen, and mirror heating is inoperable. Could it be a defective cable or plug?

I had a similar issue with my Volvo V70 (different year). Check the sensor and wiring harness. Have you done any diagnostics on the sensor readings? What values are you seeing?

Thanks for the advice. I haven't done in-depth diagnostics yet, hoping to understand common failure points first. Were your symptoms identical?

Yep, almost exactly the same. AC wouldn't kick on, and the mirror heating was dead. I’d suggest having it checked at a workshop to save time. Sounds like the same error.

I appreciate the confirmation. I suspected as much. I will have the sensor and wiring inspected at a workshop, considering the symptoms and potential cable/plug issue. I was quoted around 95€ for the sensor replacement.
