similar to the MAP sensor we want to check the
Intake Air Temp sensor next, the IAT
the stock vehicle had something called an Ambient Air Temp sensor which I think was strapped to the grill of the donor truck, unfortunately that does not make it to our LS Swapped engine wiring harness so we will rely on the Intake Air Temp instead, it's arguably a better source of signal anyway as it sits closer to the engine.
On the 3rd Gen LS engines (4.8, 5.3, and 6.0L) the IAT lives in the same housing as the MAF. It is not a separate sensor, so when you move the MAF you also relocate the IAT.
1. So once again either right click in the blank Channels pane and select Add Channel from the little pop up menu, or click the gray gear with the green plus + sign next to it on the top menu.
2. This will bring up a Channel Selector, so let's type Intake Air Temp in order to narrow down our choices, we could hunt and peck for it using the drill down method, but I find typing in what you want is quicker.
3. Then double click the Channel you want.
Again all we are going to do is just see what the IAT reads before we even start the truck, to see if it matches our Weather app on our iPhone, it should.
