Monitor 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.

Fuel Pressure Sensor Stuck Monitor 

If the fuel pressure sensor (for low pressure side) value does not follow the change in the target low pressure side fuel pressure, it is judged as a malfunction. If this malfunction is detected in 2 consecutive driving cycles, the ECM will illuminate the MIL and store DTC P107A-2A.

Fuel Pressure Sensor Correlation Monitor (Fuel Cut) 

If the fuel pressure sensor (for low pressure side) value is less than or higher than the threshold value when the fuel pump on the low pressure side is operated at the maximum during a fuel cut, it is judged as a malfunction has occurred. If this malfunction is detected for 2 consecutive driving cycles, the ECM will illuminate the MIL and store DTC P107A-64.
