Wheel speed sensor replacement

Wanted to add that for the record I have the same issue.

From a stop, you hit the gas, the power cuts and you get the traction control message on the dash + a weird noise. If you let off the gas it goes away and you can drive again.

VERY dangerous. If you try to pull out into traffic and your power cuts...it's not safe.

My Denali did the same thing when I bought it, the small dealership's trusty wrench turner couldn't fix, so it went to the dealer. The dealer diagnosed the problem and it turned out to be the entire hub assembly, not corrosion on the wheel speed sensor. Apparently, when the wheel bearing goes out, the play causes the CPU to think that wheel is turning at different speed (truck is sliding/spinning wheel).
