Monitor Description
WARNING: This page is about a different car, the 2025 Lexus NX 250, 2024 Lexus NX 250, 2023 Lexus NX 250, and 2022 Lexus NX 250. 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 less than 0.535 V for 5 seconds or more, the ECM will store this DTC.
