The automobile fault code P0AEF can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of the repair will depend on the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

The P0AEF fault code indicates a problem with the drive motor inverter temperature sensor ‘A’ circuit. The HV control ECU uses this sensor, which is built into the inverter, to detect the temperature of the motor inverter. The sensor is similar to the boost converter temperature sensor.

The HV control ECU limits the load based on the signals from the temperature sensor to prevent the inverter from overheating. The code is triggered when there is a malfunction in the wiring or the sensor itself. It is important to address this issue to ensure the effectiveness of the inverter cooling system and prevent further damage.

What are the possible causes for the automobile fault code p0aef?

If you see the engine light on or the service engine soon warning light, the fault code P0AEF 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 this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the p0aef fault code?

If you’re dealing with the p0aef fault code and your engine light is on, it’s time to take action. The possible causes include a faulty inverter with converter assembly, an open or shorted harness, a poor electrical connection in the circuit, or a faulty HV control ECU.
