Traction control engaging on dry pavement

[Tommy2Guns]

So my 2006 Tahoe reaction control comes on every time I step on the gas from a stopped position.
Today, I was driving thru town and it came on and basically stopped the vehicle. I stepped on the gas and it would not move.
I immediately switched off the reaction control via the dash button and it started to move again.
I know dirty sensors can cause this, but being unfamiliar with their locations or HOW to clean them, I'm at a loss.
Any thoughts???
Thank you in advance!

"1994 - 1999 Chevrolet Tahoe/GMC Yukon Year Models" don't have a reaction control try the newer body style part of the forum..
