DTC P0045-00: Turbo/Super Charger Boost Control Solenoid Circuit/Open: General Description
WARNING: This page is about a different car, the 2021 Kia Soul. However, it is still accessible from the selected car via links, so may be relevant.
Installed on the turbocharger, the Electric Waste Gate Actuator (EWGA) operates the vane in the Waste Gate Turbocharger (WGT) and regulates the amount of compressed air by using the ECM's Pulse Width Modulation (PWM) signal. This actuator consists of a DC motor which actuates the vane, a 2-step gear which increases torque of the DC motor, a position sensor which detects status of the vane, and an Electric Control Unit (ECU) which drives the DC motor.
