2007 International 4300 Pid171 FMI3 Ambient Air Sensor code

Hi, i have a 07 4300 which has check engine code, which is Ambient air sensor, i called Dealer they said its on the driver side mirror which i don't see the tip of the sensor from the bottom of the big mirror., some website says its in front of radiator in the driver side which is not there either.
it is the sensor hiding inside the mirror? on you youtube i saw someone changed a mid 2010s mode i can clearly see the sensor on the bottom of the mirror but mine doesnt have it.

 

I recently replaced one. It was inside the mirror I had to take the convex lower mirror out to access it.
Adjust the lower convex mirror all the was down then slide it upwards and it should come out.

 

the mirror i have doesnt have a sensor tip hanging out from the upper mirror, and all the mirror for sale on ebay doesnt have any wires came out for the sensor plug, do you have a newer model which is newer than 2015?

 

here is a picture example

 

Are you sure it isn't the Intake Air temp sensor? That is different. Those engines did not even their own Ambient Air Temp sensor for a few years yet.

What engine is this and what is the code?

 

code is Pid171 FMI3 Ambient Air Sensor

 

That is not a full code. What are you using to read it? It is missing the Source Address, (SA) or MID number

 

sorry i dont have servicemaxx, i have a diesel scanner, here is the picture

 

The one I replaced wan not visible until I removed the convex mirror.

 

So that code is actually coming from source address 23 which is from the cluster. The ambient temp sensor in this truck is only for the driver display. If you have a Check Engine light on, the engine has a code that your scanner is not able to read.
