[SOLVED] P0Aea Code: Fix Low Voltage In Hybrid/Ev Battery Temperature Sensor

The automobile fault code P0AEA indicates a problem with the HybridEV Battery Assembly. The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.

The cause of this fault code can be a faulty HybridEV Battery Assembly, an open or shorted harness, a poor electrical connection in the circuit, or a faulty HybridEV Battery Interface Control Module. To fix this issue, you should visually inspect the wiring harness and connectors for any damage.

Look for broken, bent, pushed out, or corroded pins in the connectors. The repair time for this issue is estimated to be around 1.0 hour.

It is important to address this problem promptly to prevent further damage to the vehicle.

The fault code p0aea has an estimated repair time of 1.0 hour.

Auto repair shops typically charge between $75 and $150 per hour for this type of repair.

The P0AEA fault code refers to a problem with the HybridEV Battery Temperature Sensor 4 Circuit Low Voltage. This sensor is responsible for monitoring the temperature of the battery in hybrid or electric vehicles.

It is located within the battery sections and there are two temperature sensors in each section. The sensor works by measuring the resistance of the battery cell group, which changes with temperature. As the temperature decreases, the sensor resistance increases, and as the temperature increases, the sensor resistance decreases.

The HybridEV interface control module supplies 5V to the signal circuit and acts as a ground for the low reference circuit. The HybridEV Powertrain Control Module uses the temperature sensor values to determine the battery module temperature and control the battery cooling system.

If the hybrid battery temperature sensor exceeds 160°C (320°F), the P0AEA fault code will be triggered. This indicates a low voltage issue with the sensor circuit.

It is important to address this issue promptly to ensure proper functioning of the battery and cooling system.

What are the possible causes for the automobile fault code p0aea?

If you see the engine light on or the service engine soon warning light, the fault code P0AEA 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 this issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins in the connectors. Don’t forget to also check the possible causes listed above.

How can I visually inspect the wiring harness and connectors to fix the fault code p0aea?

To fix fault code P0AEA, 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. This will help identify any issues with the Hybrid/EV Battery Assembly, its harness, or the Hybrid/EV Battery Interface Control Module. By checking these possible causes and conducting a thorough inspection, you can pinpoint and address the problem effectively.

What should I look for when checking for damaged components and connector’s pins to resolve the fault code p0aea?

To resolve the fault code p0aea, start by visually inspecting the wiring harness and connectors related to the Hybrid/EV Battery Assembly. Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins. These issues can cause a poor electrical connection or an open/short circuit. By checking and addressing these potential causes, you can fix the problem and turn off the Engine Light or Service Engine Soon Warning Light.

p0aea error fault code explained

If you notice your engine light or service engine soon warning light is on, it could be due to a faulty HybridEV Battery Assembly or a poor electrical connection in the HybridEV Battery Assembly circuit. To fix this issue, visually inspect the wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector pins.
