Don't worry about those codes. When you use a scanner or Toyota's Techstream diagnostic system it will bring up those codes. The issue occurs when the sensor that controls your automatic temperature settings and outside temperature reading don't receive a lot of direct sunlight. It's normal for this to happen. Seriously, clear those codes and try reading codes when the sun is out and shining bright on your car. You won't get those codes. Then read for codes when it's sunset or darker out. Those codes pop back up.

 

Years old i know, but i just did a read on my daughters car, and noted these exact errors.

I just wanted to jump in and say thanks for such a clear and concise answer. Gotta love it when a potential problem is answered and solved so quickly.

THnakyou!
