The factors influencing the cost of diagnosing and fixing the automobile fault code p0ae8 are the estimated repair time and the hourly rate charged by auto repair shops.

The estimated repair time for this fault code is 1.0 hour.

Auto repair shops typically charge between $75 and $150 per hour for their services.

These factors will determine the overall cost of diagnosing and fixing the p0ae8 fault code.

The P0AE8 fault code refers to a problem with the Hybrid Battery Temperature Sensor ‘D’ 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 same cooling system that cools the MG1 and MG2 is also used to cool the inverter, and the temperature sensor in the inverter is similar to the boost converter temperature sensor. The HV control ECU uses the signals from the temperature sensor to limit the load and prevent the inverter from overheating.

The code can be triggered by a malfunction in the wiring of the temperature sensor or a problem with the sensor itself.

What are the possible causes for the automobile fault code p0ae8?

If you see the engine light or service engine soon warning light on, the fault code P0AE8 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 also address the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors to fix the fault code p0ae8?

If you’re dealing with the fault code p0ae8 and your engine light is on, it’s time to visually inspect the wiring harness and connectors. This could be caused by a faulty inverter with converter assembly, an open or shorted harness, a poor electrical connection in the circuit, or a faulty HV control ECU. To fix it, check the possible causes mentioned earlier and visually inspect the wiring harness and connectors. Look out for damaged components and check for any broken, bent, pushed out, or corroded pins in the connectors.

What should I look for when checking for damaged components and connector’s pins to resolve the fault code p0ae8?
