Monitor Description

WARNING: This page is about a different car, the 2024 Lexus TX 500h. 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.
