Denali 6.0 Dead Throttle Pedal And Tract Lite Comes On!

[infinitied]

i have a 2006 Yukon Denali xl with a 6.0, it has 80,000 miles and i am the orignal owner. i perform all my own mantinance.

just recenty, the truck gas pedal goes dead when i try to acccelerate from a stop sign. and i see the traction light comming on and feel some vibrating in the brake pedal. its not all the time but its often. (is if the truck is on ice) few seconds later it stops and everything goes back to normal . (truck never shuts just sits in the idle rpm. )

i was getting the code p0101 with stinger code reader. thats all that was comming up.

(everyonce in a while even when the throttle works fine i feel that vibrating brake pedal and the truck will stay running fine)

My 06 denali does the same thing. I've read that it could be a wheel speed sensor and that there is a service bulletin for it.

your p0101 is a mass airflow performance code and may or may not have anything to do with it.

Sounds like a wheel speed sensor issue. I'm not sure if your scan tool can show data or show abs dtc's
