Monitor Description

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2024 Lexus RC 300, 2023 Lexus RC 300, 2022 Lexus RC 300, 2021 Lexus RC 300, and 2020 Lexus RC 300. However, it is still accessible from the selected car via links, so may be relevant.

If the throttle valve is closed while boost pressure is being applied, the air by-pass valve assembly opens and the excess pressure between the turbocharger and the throttle valve is released. If the boost pressure does not drop for a certain amount of time despite control to open the air by-pass valve assembly being commanded, the ECM determines that the air by-pass valve assembly is stuck closed and stores this DTC.
