Hyundai ix20 Automatic Temperature Control Failure

My 2013 Hyundai ix20 diesel's automatic temperature control stopped working. The AC won't switch on, and there's an error stored. I've read it could be the interior temperature sensor. Anyone else had sensor issues? Not sure how to proceed.

Faulty temperature sensors aren't unheard of. Have you had any recent repairs that might have disturbed the HVAC wiring? Could be a loose connection. But with that mileage, the sensor might have just failed.

Thanks! I checked the wiring as best I could, and it looks fine. No recent modifications, and the car has 186462 km. If the sensor failed, could I fix it myself with limited skills, or should I get a professional? I've changed a sensor or two before.

You're probably at the point where a professional diagnosis is needed. Even if the connections look okay, a defective cable or plug could be the cause without being obvious. Also, the error memory needs specialist tools to read. A workshop should be able to confirm the issue quickly.

Thanks for the input. I took it to a workshop. It was the temperature sensor. The mechanic replaced it, and the AC works now. Total cost was 95€ including parts and labor. I appreciate you confirming my suspicion!
