Monitor Description
WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
The power management control ECU monitors the inverter voltage (VH) sensor signal. If the power management control ECU detects a fault in the sensor signal, the power management control ECU interprets this as a VH sensor failure. The power management control ECU will illuminate the MIL and store a DTC.
