Default 07 Throttle body cleaning

Anybody have a simple write up on cleaning the TB on a 07 up ?
Dealers want too much.

You probably have drive by wire and can't actuate the plate manually is why you're asking.
I haven't tried cleaning a DBW tb yet so I'm going to offer a suggestion. Get a helper to set in the car with the key in the run position engine OFF and have helper actuate the gas pedal and see if it will move so you can spray and wipe with shop solve or similar carb cleaning solution.
I do this operation on my 2000 Silverado a couple of times a year when it starts to feel sticky when easing off of idle.

At about 85k miles, it threw a "check smog system" light. Took it to the dealer and they basically said it needed TB cleaning. Doorknobs at dealership said to have it done every 15k miles which I doubted. I have 97k now and every time it hesitates a bit, i get to thinking.

This video shows an 07 sierra, pretty much identical to my tahoe.

I'm gonna go out to the shop and do this as soon as the rig cools down. I've been having a "service traction control" problem. hard shifts and TB position sensor errors.

In this video it doesn't depict a method of cleaning the sensor in the TB sensor housing, I've heard of people having the housing seal go bad and get the sensor wet and cause all sorts of problems.
