2000-2006 GMC Yukon: Stability Traction Control System

Sun, 08 Oct 2023 17:13:17 -0700

What would cause the traction control to kick in when there isn't any wet or icy conditions?

Can I replace a sensor or module?

I do disengage this on my 2006 Yukon (a button on my console allows this), so that I can continue driving without it kicking on.

thank you, Jacqueline

Great! Thanks ABCellars - I have an AutoZone around the corner. I'll get them to check it out - go from there.

Ryan and Mayer, thank you for your input - I'll do some digging in those areas as well!

You all have narrowed down my problem - we'll go from there - let you know what I find out! Have a good one! Jacqueline

2000-2006 GMC Yukon: Why does my brake pedal go to the floor when the engine is running but

Sun, 20 Apr 2025 07:34:19 -0700

when the engine is running, my brake pedal goes to the floor. when engine is off, I can pump up the brakes somewhat. I have changed the master cylinder and there is no fluid leak. Could the problem be with the power assist boost, or is there something else that could be the issue?

Sometimes when driving my Yukon it starts to hiccup and bog down as if it's trying to stall. Occasionally it might just cough more and not stall. What's going on? I changed the mass air flow sensor; are there any other sensors I should look at?

2006-2014 GMC Yukon: 2007 Yukon 1500XL Engine Light

Sat, 18 Apr 2026 14:54:19 -0700

2007 GMC Yukon Denali 1500XL AWD
6.2L V8
187k miles

Been having some engine issues.
Replaced all 8 spark plugs, wires, coils.

Now at idle, no significant shaking.
Fuel System 1 and 2 status move to OL-Fault after a minute or so
Then traction control and stability lights come on
Followed by flashing check engine - P0300 multiple misfires

Check each cylinder report - 0 misfires on all

Get the RPMs to 2000 and the Fuel status 1 and 2 both go to CL.
The engine light goes away
The traction and stability lights go away

Drives fine. No noticeable issues other than the beeping an annoying flashing lights.

Issue seems to be air intake or fuel mix or sensors.

Short term fuel trim stays at 0.0% until the RPMs are up. Open loop fault?

O2 sensors seem sluggish - move between 0.9v and 0.2v.

MAF 0.78 to 0.83 pounds/min at idle
MAF 2.5 pounds/min at 2000 RPM

All the problems are at idle. I cleaned the throttle body, added fuel, did a battery reset. What else?

I threw all this into AI and it says I need to replace the front two O2 sensors. But what do humans think?
