Faulty Turbo Boost Control Solenoid Valve
Turbo Boost Control Solenoid Valve harness is open or shorted
Turbo Boost Control Solenoid Valve circuit poor electrical connection
Faulty Waste Gate
Faulty Engine Control Module (ECM)
Engine Light ON (or Service Engine Soon Warning Light)
This fault code is stored in the Engine Control Module (ECM) when a fault is detected with the wastegate control solenoid circuit. The purpose of the control system is to limit the boost pressure to allow for optimum performance without the risk of engine damage due to excessive boost pressure. The electrical circuit is monitored for open circuit, short circuit, and high resistance conditions.
