What Does the P0048 Code Mean?

The positions of the turbocharger vanes are controlled by the Engine Control Module (ECM). The ECM utilizes a turbocharger vane control solenoid to control the turbocharger vanes and a turbocharger vane position sensor to verify the position of the vane. The ECM will vary the boost depending upon the load requirements of the engine. The vane control solenoid has a high control circuit and a low control circuit. The ECM uses a pulse width modulation on both circuits to control the solenoid. The Diagnostic Trouble Code (DTC) will set if the ECM detects that the commanded state of the driver and the actual state of the control circuits do NOT match or if the condition exists for equal to or greater than 4 seconds.
