DTC P0AEF-275: Drive Motor Inverter Temperature Sensor "A" Circuit Low; DTC P0AF0-274: Drive Motor Inverter Temperature Sensor "A" Circuit High [11/2016 - ]: Description
WARNING: This page is about a different car, the 2019 Toyota Highlander, 2018 Toyota Highlander, and 2017 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
The MG ECU, which is built into in the inverter with converter assembly, detects the temperature of the motor inverter using a temperature sensor built into the inverter with converter assembly. The inverter cooling system operates independently of the engine cooling system. The MG ECU uses signals from the motor inverter temperature sensor to check the effectiveness of the inverter cooling system. If necessary, the MG ECU will limit inverter output to help prevent inverter overheating. The MG ECU also detects malfunctions in the motor inverter temperature sensor and its wiring.
