P0A80 is one of the most common hybrid battery codes on vehicles like the Toyota Prius, Camry Hybrid, Highlander Hybrid, and some Lexus models. It usually means the car’s computer has detected one or more weak blocks inside the high-voltage battery.
P0A7F generally means the computer has calculated that the hybrid battery has lost a significant amount of capacity compared to when it was new.
P3000 is a general hybrid control system code that is usually set along with more specific hybrid battery codes.
P0A90 usually indicates a performance problem in the hybrid drive system — sometimes related to the transmission, electric motors, or control system.
P0A1F points to an issue in the hybrid powertrain control module or its communication. It can be wiring-related, module-related, or triggered by other system faults.
P0A0F means the system tried to start the engine and could not. This can be due to engine issues, fuel problems, sensors, or related hybrid control problems.
P0A93 usually means the inverter cooling system is not working correctly (e.g., failed pump, low coolant, or flow issue).
