I have a 05 TL and can't find the IAT (Intake Air Temp) sensor or any DIY on how to replace it... HELP! I'm changing this and the "Bank 1 Sensor 1" sensor this weekend.

 

what makes you think the IAT is bad?

and its on the throttle body. but more interested in why you think its bad.....
and the bank 1 sensor 1 is called an 02 sensor.

 

Damn you Justin. Haha! The "Bank 1 Sensor 1" is an "Air/Fuel Sensor. Not just O2 sensor. . But I had a diagnostic run on my car and both the IAT and O2 sensor are bad.

The dealership kept correcting me when I'd call it an O2sensor. Haha

 

oxygen = air?

O2 sensor

it measures the Oxygen or O2/Air in the fuel.


if they kept correcting you on a "splitting hair issue" like calling it an air/fuel sensor...I would be worried if they diagnosed your car wrong.
is your check engine light on?
does the car run like crap?

 

Yeah I know man. Just giving you a hard time. Any idea where I could find instructions pictures or any DIY to replace them? Searched the forum and google and no luck.

 

That guy that's on the throttle body.


and yep, that's my car!
hope this helps!

 

Justin my man you are awesome!!!

 

Pass on your newly found knowledge to others!

 

Here's a DIY for the O2 sensor. Probably the more difficult of the two O2 sensors to replace they seize up pretty good sometimes.

Did they tell you the codes that were set for your check engine light?
