Circuit/System Verification

Inspect for any damage, improper routing or connecting of the vacuum hoses on the turbocharger bypass valve solenoid and the turbocharger bypass valve.
Use the scan tool output controls to command the TC Bypass Solenoid ON and OFF. An audible click should be heard and felt.
Set up the scan tool for a snapshot of the induction data list. With the emergency brake on, the vehicle transmission in neutral, and the engine idling, perform a wide open throttle and then quickly release the accelerator. Review the Boost Pressure Sensor parameter and look for any abnormal pulsations of the parameter.
