P0034



The ECM detects the bypass solenoid valve control circuit is shorted to ground.



P0035



The ECM detects the bypass solenoid valve control circuit is shorted to voltage.



Action Taken When the DTC Sets



DTC P0033, P0034, and P0035 are Type B DTCs.



Conditions for Clearing the DTC



DTC P0033, P0034, and P0035 are Type B DTCs.



Diagnostic Aids



If the condition is intermittent, move the related harnesses and connectors, with the engine operating, while monitoring the circuit status for the



component with a scan tool. The circuit status parameter changes from OK or Not Run to Malfunction if there is a condition with the circuit or a



connection.

Circuit/System Verification



Note: If any Turbocharger circuit DTC is set, the Bypass Solenoid Valve output control may not function. It may be necessary to clear the



DTCs with a scan tool to enable the output control.



1. Ignition ON, observe the DTC information with a scan tool. Verify that DTC P0234, P0299, P0236, P0237, P0238, P0244, P0245, or P0246



is not set.



瀚慖f a DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code Descriptions/Diagnostic Trouble



Code (DTC) List - Vehicle) for further diagnosis.



2. Ignition ON, command the Turbocharger Bypass Solenoid Valve between Inactive and Active with a scan tool. You should hear an audible



click.



3. Engine running, command the Turbocharger Bypass Solenoid Valve between Inactive and Active with a scan tool while observing the



following control circuit status parameters:



* Turbocharger Bypass Solenoid Valve Control Circuit High Voltage Test Status
