P2599 CHEVROLET Description
The position of the turbocharger vanes is controlled by the Engine Control Module (ECM). The ECM utilizes a turbocharger vane control solenoid valve to control the turbocharger vanes, and a turbocharger vane position sensor to verify the position of the vanes. The ECM will vary the boost dependent upon the load requirements of the engine. The turbocharger vane position sensor provides the ECM with a signal voltage relative to the vane position. The Diagnostic Trouble Code (DTC) will set if the ECM detects that the difference between actual vane position and desired vane position is less than 15% for greater than 10 s.
