Traction active light!!

[kyle fiore]

i have a 2003 Yukon Denali. Recently started saying traction active on dash and losing complete power and will suddenly come back to life and be fine, when almost to a complete stop it jerks the wheel to the left and peddle acts as if I'm sliding and abs light kicks on. If I turn tc off it accelerates fine as it should, if I pull abs fuse it stops normal. I've replaced both front hub assemblies with new speed sensors what else could it be???

Also I use this as my snowboard rig this time of year if I turn my tc off is it still AWD or how does that work?

Oh man, I just went through this. And found it could be anything from the TPS, to the pedal sensor, to a bad ground. Oddly, when mine would happen I could plug in my scanner, clear the code, and it ran fine. Eventually I replaced the TPS and the wiring harness and *knock on wood* it's been fine since. That was only a few weeks ago though...

rear speed sensors? I tore a wire and soldered it back up and mine comes on periodically. I always just let off the throttle for a second and it was fine. Have not gotten around to replacing it.
