P0Af4 Fault Code: Understanding The Hybrid/Electric Vehicle Battery System Issue
The P0AF4 fault code refers to a problem with the Drive Motor Inverter Temperature Sensor ‘B’ Circuit.
This sensor is located in the inverter and is used by the HV control ECU to monitor the temperature of the motor inverter.
The inverter is cooled by the same system that cools the MG1 and MG2, and this cooling system is separate from the engine cooling system. The motor inverter temperature sensor has the same characteristics as the boost converter temperature sensor.
The HV control ECU uses the signals from this sensor to limit the load and ensure the effectiveness of the inverter cooling system, preventing it from overheating.
The code is triggered when there is a malfunction in the wiring of the motor inverter temperature sensor or in the sensor itself, causing the circuit to register a low temperature reading.
FAQ
If you see the engine light or service engine soon warning light on, the fault code P0AF4 could be the culprit.
