Condition/Concern
In rare cases, some customers may comment about the Service Stabilitrak message being displayed in the DIC. The StabiliTrak® Indicator light may also be
on.
When checking the vehicle for DTCs, the electronic brake control module (EBCM) may report C0455 and/or C0710 set as current or in history.
This condition may be caused by an increase in resistance in the circuits connecting the steering position sensor and the EBCM due to fretting corrosion on the
connector terminals.
Also, the male to female plastic connector may have excessive clearance that can cause the connector to move up and down.
Note: Fretting corrosion looks like little dark smudges on the electrical terminals and appear where the actual electrical contact is being made. In less severe
cases it may be unable to be seen or identified without the use of a magnifying glass.
Recommendation/Instructions
Important: DO NOT replace the steering position sensor for this condition. The terminal pins on the sensor do not have the same concentration of deposits.
1. Disconnect the steering wheel position sensor connector.
1
2. Add a piece of Adhesive Back Shim Stock the width of the connector to the flat surface on the male connector. This provides support to the connector
to keep it from moving up and down.
Important: DO NOT apply an excessive amount of dielectric lubricant to the connector, as hydrolock may result when attempting to mate the
connector. Use ONLY a clean nylon brush that is dedicated to the repair of this specific condition.
3. With a nylon bristle brush, apply dielectric lubricant to both the sensor side and the harness side of the affected connector.
4. Reconnect the steering wheel position sensor connector and wipe away any excess lubricant that may be present.
5. Attempt to duplicate the condition by using the following information:
– DTC Diagnostic Procedure
– Circuit/System Description
– Conditions for Running the DTC
– Conditions for Setting the DTC
– Diagnostic Aids
– Circuit/System Verification
If the condition cannot be duplicated, the repair is complete.
If the DTC resets, replace the steering angle sensor harness side connector with the service pigtail. Refer to the Steering Angle (Position) Sensor connector
end view in SI for the correct service connector part number.

What do you do for a bad steering wheel position sensor. I can not find one for my 2007 Chevy Avalanche LTZ 5.3liter 4×4.
Everywhere I look say they have quite making or carrying it.
This is the part # 15886733, Some places still sell it on line.
I cannot find a steering wheel sensor for my 2009 GMC Sierra! Why are they not making them?
By law they only have to make parts for 10 years. You can try https://car-part.com/
