22008 gmc envoy denalI steering wheel sensor

[Jatsr]

Is it possible to calibrate a steering wheel sensor on a 2008 gmc envoy denali 5.3,

Or is just a replace situation.

I'm not sure I know what that is ....

 

Electric steering wasn't around in '08 that I'm aware of.

Replace it, a very common failure item.

What sensor, Mike?

[mjm-1957]

The steering wheel position sensor located at the bottom of the steering column.

I was under the impression they only used those on electric power steering vehicles. Learn something new every day with these computer controlled, beer-can-clad rolling Tupperware ... 

 

What is the purpose of that on a traditional belt-driven hydraulic power steering system?

[mjm-1957]

The Denali has a variable ratio steering rack that uses the input from the steering wheel position sensor to vary the rate of assist and also the stabiltrack uses it in conjunction with the Yaw sensor and brake input to apply the brakes on the inside wheels in a high speed turn if certain conditions are met so the driver can regain some control.

AHH, now I get it. Basically for stability control. Thanks, Mike!
