Avalon automatic temperature control issue

I had a similar issue with my Avalon. Check the cable and plug connection of the sensor. That was the problem for me. Is the error message related to the HVAC sensor?

Thanks for the tip! Where exactly is the sensor located? And how did you figure out the cable was the issue? Was it visibly damaged?

Mine was tucked up behind the dash, near the center console. Honestly, I didn't diagnose it myself; I took it to a shop. They found the loose connection pretty quickly. Cost me 95€ to get it sorted. Might be worth getting it checked out professionally.

Thanks, I appreciate the advice. I ended up taking it to a mechanic, and you were right – it was a loose connection on the sensor! They fixed it, and everything is working perfectly now.
