The P0AF3 fault code refers to a problem with the Drive Motor Inverter Temperature Sensor ‘B’ Circuit RangePerformance. This sensor is located in the inverter and is responsible for detecting the temperature of the motor inverter. It uses the same cooling system as the MG1 and MG2, which is independent from the engine cooling system.

The HV control ECU uses the signals from the motor inverter temperature sensor to limit the load and prevent the inverter from overheating. It also detects any malfunctions in the wiring or the sensor itself.

This code indicates that there is an issue with the circuit range or performance of the temperature sensor.

It is important to address this problem to ensure the proper functioning of the inverter cooling system and prevent any potential damage or overheating.

What are the possible causes for the automobile fault code p0af3?

If you see the engine light or service engine soon warning light on, the fault code P0AF3 could be the culprit. This code is often caused by a faulty inverter with converter assembly, an open or shorted harness, a poor electrical connection in the inverter with converter assembly circuit, or a faulty HV control ECU. To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins. Don’t forget to consider the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors to fix the p0af3 fault code?
