WARNING: This page is about a different car, the 2025 Toyota RAV4, 2024 Toyota RAV4, 2023 Toyota RAV4, 2022 Toyota RAV4, and 2021 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
The ECM monitors the engine oil temperature sensor and uses the sensor voltage to calculate the engine oil temperature. If the engine oil temperature sensor output voltage deviates from the normal operating range, the ECM determines that the engine oil temperature sensor (oil pressure and temperature sensor) circuit is malfunctioning and stores this DTC.
Example:
If the engine oil temperature sensor output voltage is less than 0.535 V for 5 seconds or more, the ECM will store this DTC.
