You are in the GMC Yukon
What is this discussion about?
GMC Yukon Denali, SUV
#1 of 53 2004 GMC Yukon XL Denali Traction Control
Feb 25, 2009 (9:05 am)
At a stop sign or a green light, when I accelerate slowly, the engine cuts power and the "traction control" displays on the computer. This only happens intermittently, and always when conditions are dry and sunny (I live in Florida). It behaves as if I were accelerating on glare ice and the wheels were slipping. To overcome the problem on the scene, I either give it more gas (as the problem happens only on light throttle) or I de-activate the traction control via the button on the dash.
Has anyone had this problem? If so, what is the fix? A bad sensor or a bad traction control module?

By the way, the OBD II diagnostic computer can detect NO ERROR CODES!

I have the exact same problem! Have you found any answers yet?

I have the same problem too. It is very annoying. I haven't yet taken it in to the shop, but I am not having a good feeling about what will come about from it. I have already had to replace the transmission in the truck, and mass airflow sensor. Now the air conditioning compressor has a hole in it, so the A/C doesn't work and the front wheel bearings are going out, so, I am not very impressed with the truck.

It seems that the general consensus is that the speed sensors on the front wheels are corroded and that this gives the computer a faulty signal about the actual speed of each wheel, thereby engaging the traction control. The solution is to clean the sensors. I have not yet had time to do this, as it is a lengthy job taking apart the front brakes, etc. For now, when the problem happens, I just reach over and disable the traction control.
Sorry to hear about the problem with the MAFS and the A/C. Both those parts are not cheap.

I had this same problem and cleaned the front wheel speed sensors.
That worked for about 1000 mi then it started again. After two times to the
local dealer ( they could not find any problem ) and $ 125.00 later . I decided to
take a chance and replace the front sensors ( approx. 2 hours in my garage )
and cost approx. $110.00 ( for the set of 2 )at my local chevy dealer. He needed the vin to locate the correct part and it took a couple of days to get. of course they are made in
Taiwon . That completely corrected my "traction control " problems. I have driven
approx. 4000 mi with no problems except for the rear wiper that doesn't work.
73,676 mi and gets 17.5 on the highway.

Thanks for the advice. When you removed the sensors, did you first remove the hub and the half shaft, or do the sensors come out without having to take apart the hub?

you can remove the sensors by first removing your front brake caliper and then removing your rotor, the sensor is attached to the hub with a single allen bolt. I installed the new ones with " loctite " to be sure they stayed in place. This is the setup on my 2004 yukon denali.
I got to cut grass now so i will check back in 1 to 2 hours.

Thanks again for the advice. I will tackle the job in a few days. Right now my son is occupying our hoist.

Replaced the front left sensor. Reused the front right as it looked really good. Still have the problem with traction control active. Will try replacing the front right sensor.
