SPOOLOGIC VGT Solenoid

The SPOOLOGIC VGT Control Solenoid - SL-270-006 meters engine oil to the turbocharger vane mechanism on the listed 2004.5-2016 Duramax applications. It replaces the separate electro-hydraulic solenoid used to control vane movement.

VGT Control

The solenoid meters engine oil to the hydraulic mechanism that moves the turbocharger vanes. The separate vane position sensor reports actual vane position to the engine controller; it performs a different function from the control solenoid.

Common VGT Control Fault Codes

• P0045: Turbocharger boost-control solenoid circuit fault.
• P0046: Turbocharger boost-control solenoid circuit range/performance.

Code availability varies by model year and calibration. A stored code does not prove the solenoid has failed.

Diagnose Before Replacing

Inspect the solenoid connector and wiring, engine oil condition and supply, and the vane mechanism. Compare commanded and actual vane position with a capable scan tool. A sticking vane mechanism or oil-supply problem can cause poor response even when the solenoid operates correctly.

Installation Notes

Keep debris out of the solenoid bore and oil passages. Inspect the seals, install the retaining bracket and bolt, and follow the GM service procedure for the specific turbocharger. Verify vane response after completing the repair.
