Monitor Description

WARNING: This page is about a different car, the 2025 Lexus NX 350h, 2024 Lexus NX 350h, 2023 Lexus NX 350h, and 2022 Lexus NX 350h. However, it is still accessible from the selected car via links, so may be relevant.

The ECM monitors the speed of the engine water pump assembly. When the speed becomes a certain value or more, the ECM judges that the speed is abnormally high and stores a DTC (The MIL does not illuminate).
