Monitor Description

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

The ECM monitors the speed of the electric water pump assembly. If the actual speed exceeds the target speed by a certain amount or more, the ECM determines overspeed operation has occurred. If the actual speed is less than the target speed by a certain amount or more, the ECM determines that the motor is stuck and stores a DTC.
