WARNING: This page is about a different car, the 2024 Lexus IS 500, 2023 Lexus IS 500, and 2022 Lexus IS 500. However, it is still accessible from the selected car via links, so may be relevant.

If the fuel pressure increases despite a decrease request signal being sent to the fuel pump (for high pressure) by the ECM, the ECM will illuminate the MIL and store this DTC.
