Code P2599 2018 Chevrolet Silverado Description

A smart turbocharger vane position actuator incorporates a brushless motor and is mounted on top of the turbocharger. It is connected to the vanes by a linkage rod. The vanes are used to vary the amount of boost pressure and can control the boost pressure independent of engine speed. The vanes mount to a unison ring which is rotated to change the vane angle. The Engine Control Module (ECM) communicates with the actuator via the Controller Area Network (CAN) bus. The ECM will vary the vane angle which adjusts the boost dependent on the load requirements of the engine. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the actual turbocharger vane position is 25% greater than the turbocharger learned closed vane position, for greater than 10 s after P0046 sets.
