P0071 Ambient Air Temperature Sensor Range/Performance
 

erased the code but the check engine light cames back on after a day.
assuming the sensor have to be changed does anyone know where it is located?
thanks

Still driving with the SES light on. I heard this code is caused by a bad sensor, in one of the mirrors for dashboard temp. display? Seams like the temp is displayed correctly though.
Can someone please confirm this.

Solved
 

Here is how to replace the sensors. These are located in the mirrors, P0071 is in the L.H. mirror and P0072 in the R.H. I just replaced them both after getting the second ecm P0072.
Hope this helps someone.
