Turbocharger Vane Position Sensor

WARNING: This page is about a different car, the 2010 GMC Sierra, 2010 GMC Cab & Chassis Sierra, 2010 Chevrolet Silverado, and 2010 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The ECM uses the turbocharger vane position sensor to monitor the TC vane angle. The voltage is low when the TC vanes are open, and high when the TC vanes are closed.
