C0710 Steering position sensor erratic

GM has determined that the electrical connector to the steering position sensor may experience “fretting” corrosion. That happens when the metal terminal connectors rub against each other and generate metallic dust that can cross connect other terminals. The fix for fretting corrosion is to use a clean nylon brush and brush away all traces of dust and then apply a very light film of dielectric grease to lubricate the terminals and prevent electrical cross connections.

In this particular case, GM has determined that a slight bit of slop in the connector can cause it to vibrate, resulting in this rubbing. In addition to cleaning and applying dielectric grease, GM wants you to add a piece of adhesive backed shim stock to the flat surface on the connector so when it’s connected, it creates a tighter fit and eliminates vibration.

GM warns NOT to replace the steering position sensor—that the trouble code is most likely the result of fretting corrosion. Also, GM warns not to apply too much grease—that will prevent the connectors from mating all the way.
