The P0AE6 fault code indicates an issue with the Hybrid Battery Precharge Contactor Control Circuit, which is responsible for controlling the electrical connection between the hybrid battery and the rest of the hybrid vehicle's power system. When this circuit is low, it can lead to a variety of performance issues with the hybrid system, including reduced power output and potential failure to start the engine.

What are the symptoms of the P0AE6 code?

Common symptoms associated with the P0AE6 fault code include: • Warning lights illuminated on the dashboard (often the check engine or hybrid system warning light) • Decreased fuel efficiency and vehicle power • Engine may not start or may have difficulty starting • Unusual noises from the hybrid battery system • Increased emissions from the vehicle.

What causes the P0AE6 code?

Several factors can lead to the P0AE6 fault code, including: • A faulty precharge contactor • Damaged wiring or poor connections in the control circuit • Issues with the hybrid battery or battery management system • Problems with the vehicle’s electronic control unit (ECU) that may affect contactor regulation • Corrosion or moisture that affects electrical connections.

How to fix P0AE6?

To resolve the P0AE6 fault code, consider the following steps: • Inspect the precharge contactor for damage and test its functionality • Check the wiring and connections in the control circuit for any signs of wear, corrosion, or loose connections • Test the hybrid battery and battery management system to ensure they are working properly • Update or reprogram the ECU if necessary • In some cases, replacing faulty components may be required.
