DTC P008A-00: Low Pressure Fuel System Pressure - Too Low [11/2019 - ]: 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.

In order to supply the optimal fuel pressure according to the driving conditions and usage environment, the variable fuel system sends a drive signal from the ECM to the fuel pump control ECU, steplessly performing variable control of the fuel pump (for low pressure side) and receiving feedback about the fuel pressure (for low pressure side) from the fuel pressure sensor (for low pressure side).
