If your still getting an error for the sensor..........the first thing I would recommend is trace the wiring harness back to where it joins the main hanress.

Look to see if its damaged in anyway

What P code are you getting?

I cant really make a guess without knowing if it's a correlation between sensors, a bad heater circuit, or a malfunction code.

Op most auto parts stores will read your codes if you don't have a scan tool.Write down the exact code or codes and report back.
