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
