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 high pressure side) value does not follow the change in the target high 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 P0190-2A.

Fuel Pressure Sensor Correlation Monitor with Atmospheric Pressure 

If the fuel pressure sensor (for high pressure side) value is less than or higher than the threshold value when a cold start is performed after the engine has been warmed up and then stopped, 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 P0190-64.
