WARNING: This page is about a different car, the 2024 Lexus TX 550h+. 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 (engine room side) pump assembly (for high pressure side) by the ECM, the ECM will illuminate the MIL and store this DTC.
