DTC P0033-12: Turbocharger / Supercharger Bypass Valve "A" Control Circuit Short to Battery; DTC P00C0-12: Turbocharger/Supercharger Bypass Valve "B" Control Circuit Short to Battery [12/2017 - ]: Description
The air by-pass valve assembly is installed in the air outlet duct. It opens and closes in response to drive commands from the ECM. During normal boosting, the air by-pass valve assembly is closed, and when the throttle valve is closed while the boost pressure is applied, the air by-pass valve assembly opens and the excess pressure between the turbocharger and throttle valve is released to prevent the surge phenomenon*.
*: This phenomenon is when the intake air flow reverses. As a result, an abnormal noise is easily generated during deceleration.
