Monitor Description
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Lexus UX 250h, 2023 Lexus UX 250h, 2022 Lexus UX 250h, 2021 Lexus UX 250h, and 2020 Lexus UX 250h. However, it is still accessible from the selected car via links, so may be relevant.
The ECM monitors the engine oil temperature sensor (engine oil pressure and temperature sensor) and uses the sensor voltage to calculate the engine oil temperature. If the engine oil temperature sensor (engine oil pressure and temperature sensor) output voltage deviates from the normal operating range, the ECM determines that the engine oil temperature sensor (engine oil pressure and temperature sensor) circuit is malfunctioning and stores this DTC.
Example:
If the engine oil temperature sensor (engine oil pressure and temperature sensor) output voltage is higher than 4.865 V for 5 seconds or more, the ECM will store this DTC.
