Steering Wheel Position Sensor Replacement

Has anyone replaced their own steering wheel position sensor? How long does it take, what is involved and are there any special tools needed?

I may be able to tell you shortly. The steering position sensor is just another of a long list of things that have failed on my 07 Envoy. Makes me wish I bought a Toyota...

Ok, here ya go. You need to straighten the steering wheel and lock it with the key. There is a special tool that can be inserted through a hole in the bottom of the column to stop the steering wheel from moving but I don't think it is necessary. Remove the lower dash cover with the vent hose and you will see the lower intermediate shaft boot. Slide the boot back and you will see the coupler with a pinch bolt holding the upper intermediate shaft to the steering column shaft. Remove that pinch bolt and remember its position. Slide the upper intermediate shaft off the steering column shaft and remove it. You should see the steering wheel position sensor at this point. It is held on with two screws. Remove the bracket and sensor. The new sensor comes with a lock pin installed in it so do not remove it until you install it onto the column. According to the labor manual it takes .9 hour to do the job. .6 for warranty work. It looks pretty straightforward. I don't know if I am going to replace mine or trade it off since it has been a maintenance nightmare. If I do decide to replace mine I will share more info.
If you have a digital camera you can take pictures during the disassembly so you can refer back to them during re-installation.

Steering position sensor (stabilitrack)

I purchased an envoy that had been hit in the left front wheel. The accident broke an internal part in the rack and pinion allowing the steering wheel to slip and rotate excessive turns.

I replaced the rack and assorted suspension components, now the stabilitrack lights come on anytime the steering wheel is turned. I am guessing based upon the information in the post above that the sensor is now misaligned, damaged or both. Does anyone have a re-learn or reposition procedure for this?

Thanks,
Dan

Parts numbers and exploded views are available on www.compnine.com

Good luck! Sure your clockspring isn't broken as well from the excessive rotations?

Probably a GM-only part so Rock Auto won't have it. See post #7 for your answer.
