P0AEA Fault Code

Hybrid Battery Temperature Sensor "D" Circuit Low

• What does that mean?
• Symptoms
• Causes
• Solutions

The P0AEA fault code indicates a fault in the Hybrid Battery Temperature Sensor "D" circuit, specifically signaling that the temperature reading from sensor "D" is lower than the expected operational range. This could imply an issue with the sensor itself, the wiring, or the electronic control module (ECM) not receiving the correct signal.

What are the symptoms of the P0AEA code?

Common symptoms associated with the P0AEA code may include:

• Warning lights illuminated on the instrument panel, specifically the hybrid system warning light
• Decreased performance of the hybrid system
• Heating or cooling issues in the hybrid battery pack
• Possible disruptions in fuel efficiency due to improper battery management.

What causes the P0AEA code?

Potential causes for the P0AEA code include:

• Faulty Hybrid Battery Temperature Sensor "D"
• Damaged wiring or connectors in the sensor circuit
• Poor connection or corrosion at the sensor or ECM connections
• ECM failure or software issues that affect sensor data processing.

How to fix P0AEA?

To resolve the P0AEA code, the following steps are generally recommended:

• Inspect and test the Hybrid Battery Temperature Sensor "D" for functionality and accuracy
• Check the wiring and connectors associated with the sensor for signs of damage or corrosion
• If necessary, replace the temperature sensor and clear the fault code using an OBD-II scanner
• Perform a system reset or recalibration if required, and monitor for the recurrence of the code.
