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 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).
