Looking for location of iat sensor


I am not too familiar with this engine, but iat's are usually somewhere between the airbox and throttle body, I know on older gm trucks it's in the airbox. You should see a two wire connector.

Which 2 wires is The IAT on 2007 Silverado


The intake air temp sensor is the one that is not the mass air flow. It should be a little 2 wire sensor in the inlet tube. The mass air flow is near the air cleaner, and is inline with the air inlet tube.
