Hello. I just got my first "check engine light." I read it on my Superchips and it said P0071, air temp something. I did a search and I found comments about a dirty element. Any info people?
Thanx.

 

my tuck just took a dump too...with similar codes.....

Interesting ******. I did a fuel filter/oil filter, and oil change right beforehand. Weird.

Thanx.

 

Mine has done the 0071 (air temp rational) and the 0514 (battery temp rational) from time to time. Every time it has done it was when the temperature has really fallen overnight. I figure when the garage is open, the cold air gets to the engine during start-up. It is impressive that the sensors can be that sensitive. I just got a scanner from Auto Zone to get rid of the light and bell. The light goes out by itself after something like 10 starts.

 

did you unplug your IAT sensor to get to your oil filter?????

 

I will look when I get home to see if I see a loose wire.
Thanx.
