Caution / Notice / Hint
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.
HINT:
- If any of DTCs P0115-11 or P0115-15 are output simultaneously with DTC P0125-00, the engine coolant temperature sensor may have an open or a short circuit. Troubleshoot those DTCs first.
- Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
