DTC P0AF2-11: Drive Motor Inverter Temperature Sensor "B" Circuit Short to Ground; DTC P0AF2-15: Drive Motor Inverter Temperature Sensor "B" Circuit Short to Battery or Open [12/2019 - 11/2023]: Description

The motor generator control ECU (MG ECU), which is built into the inverter with converter assembly, detects the temperature of the rear motor inverter using the rear motor inverter temperature sensor. The inverter cooling system operates independently of the engine cooling system. The motor generator control ECU (MG ECU) uses signals from the rear motor inverter temperature sensor to check the effectiveness of the inverter cooling system. If necessary, the motor generator control ECU (MG ECU) will limit inverter output to help prevent inverter overheating. The motor generator control ECU (MG ECU) also detects malfunctions in the rear motor inverter temperature sensor and its wiring.
