Monitor Description

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

If the boost pressure exceeds the threshold value (calculated from turbocharger speed upper limit value or compressor downstream temperature upper limit value), there may be a malfunction in the turbocharger system. In this case, the ECM stores this DTC.
