The factors influencing the cost of diagnosing and fixing the automobile fault code p0ae9 are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges from $75 to $150.

The P0AE9 fault code refers to a problem with the HybridEV Battery Temperature Sensor 4.

This sensor is responsible for monitoring the temperature of the battery cell group within the hybrid or electric vehicle. It is a variable resistor that measures the temperature, with its resistance changing as the temperature fluctuates.

There are two temperature sensors located in each battery section, and they communicate their values to the HybridEV Powertrain Control Module.

This module uses the sensor readings to determine the overall temperature of the battery module and control the operation of the battery cooling system. The P0AE9 code is triggered when there is a significant difference of more than 25°C (45°F) between one battery temperature sensor and the average of the other sensors.

This indicates a performance issue with the HybridEV Battery Temperature Sensor 4. It is important to address this fault code promptly to ensure proper functioning of the battery and cooling system.

What are the possible causes for the automobile fault code p0ae9?

If you see the engine light or service engine soon warning light on, the fault code P0AE9 could be the culprit. This code is often caused by a faulty Hybrid/EV Battery Assembly, an open or shorted harness, a poor electrical connection in the Hybrid/EV Battery Assembly circuit, or a faulty Hybrid/EV Battery Interface Control Module. 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.
