I have a 2008 Chevy Impala SS with a 5.3L V8. I am trying to find the location of the throttle position sensor, but have had not luck. Can you tell me where it is located on this engine application?

SOURCE: on a 2006 chevy impala it tells you to tighten the gas cap

There is no sensor for a loose gas cap. What is happening is that the evaporative emission system is sensing a "Large Leak". Usually code p0455. The computer sees this as the most probable cause is a loose gas cap depending on several factors it looks at. You would need to clear the code(s) and see if that was the problem. If the light comes back on, then you have a problem in the system that will not let it seal. Possible solenoid problem, leaking hose / line, etc.

Yes. That is exactly it. The Air Intake Temp Sensor is built into the Mass Air Flow Sensor on the Air Filter Box. Below is a picture...


I personally have not connected one of these Chips to a Tahoe...What I can provide you with, is the Connector Diagram so you know exactly what Wires you need to Splice in to. See below...

I hope this helps you. If you have any more questions or need any more diagrams, please don't hesisitate to ask...Thanks again, JShreader.
