An improvement has been implemented to the turbocharger vane position sensor. Some turbochargers existing in inventory have the old style vane position sensor.

If turbochargers, GM P/N 12635325 or 12635167 are being replaced, the original turbo vane sensor should be removed and replaced with the new style sensor, GM P/N 12643471. Turbochargers that are supersessions to these part numbers will have the new style vane position sensor and no action is necessary.
