Throttle body cleaning and relearn/reset

[edizzle89]

What is the recommended way to clean carbon from the throttle body and is there a real learn/reset procedure? I'll be put in my new cold air intake on soon and I figured I would clean and reset it while I was in there.

anybody have any info on this?

I have done mine a few times. Simply clean it out using Throttle Body cleaner or Seafoam spray and carefully open the butterfly and wipe all around. Then with the car on and fully hot, I will spray in a can of Seafoam Spray through the throttle body being careful to not let the engine stall completely.
No " relearning" or anything you need to do. Just be gentle when opening the butterfly valve (when the engine is off) to wipe away carbon

Wondering this too... I heard you aren't supposed to move the ETB's even when they're disconnected let alone when they're connected and the car on. My throttle valve only opens about 25% when I full matt with the car in the "On" position (Not running for obvious reasons). Is this normal and are you sure there isn't a relearn procedure?

I unbolted the throttle body and cleaned both sides of it. I also moved the butterfly when cleaning it. There was no issues doing this.

The Genesis sedan 3.8 (2015...) workshop manual has a drawing that shows the zones that can be hand wiped with approved type cleaner. It warns about cleaning - presumably, also hosing down with such things as SeaFoam - the pivot points of the butterfly, which are 'dry bearings', which have a coating intended to minimize air leakage.
