The P0A80 code displays when the Powertrain Control Module (PCM) detects a malfunction in the hybrid vehicle battery management system or the battery cells.
The trouble code simply indicates that the vehicle’s battery pack has deteriorated and you need to repair or replace it.
What Does Code P0A80 Mean?
Diagnostic trouble code (DTC) P0A80 stands for “Replace Hybrid Battery Pack.”
The diagnostic trouble code P0A80 indicates that your hybrid battery is failing and must be replaced. The code P0A80 might show alongside others, such as P3011-P3024, which indicate issues with a specific block of modules/cells that are causing the failure.
If the powertrain control module detects an issue with one or more cells within the battery pack, the check engine light will likely turn on, and your car might give you one or more of these error codes.
Here are some common error codes relating to the hybrid vehicle battery:
- P0A80
- P3000
- P3011 – P3024
- P3030

Causes of a P0A80 Code
The causes of a P0A80 trouble code vary widely from car to car, depending on the state and design of the battery. The most common causes include:
- Deterioration of the battery over time – Hybrid battery packs degrade over time which also reduces their capacity. The reduced capacity, plus loss of overall battery performance can trigger a P0A80 warning.
- Battery cell failure – The presence of any weak cells within the pack can affect the performance of the entire battery pack, which can cause major battery pack issues and trigger code P0A80.
- Individual cell resistance – Inconsistencies in the internal resistance of the cells may lead to major voltage differences, which the PCM may interpret as battery failure.
- Battery temperature – The fault code may also be triggered when the temperature of the battery cells goes too high or too low.
- Malfunctioning Powertrain Control Module (PCM) – The PCM is responsible for receiving signals from the battery management system and turning on the check engine light. If it malfunctions, it may misinterpret the data and wrongfully save the error code.
- Bad battery replacements – If a brand-new battery or a remanufactured battery replacement is not installed correctly, it can trigger a P0A80 code.
- Defective battery pack fans – The fans that help cool the battery pack can malfunction, causing the battery pack to overheat and the PCM to set a P0A80.
What are the Common Symptoms of the P0A80 Code?
A P0A80 code, by affecting the car’s primary source of electrical power, often has very noticeable symptoms. Here are some of them:
- Check engine light illumination
- Significant decrease in fuel economy
- Inconsistent battery charge level or battery level indicator
- Repeated battery temperature or voltage sensor warnings
- Electric propulsion system not functioning properly
- Busbar connector sections showing signs of corrosion or damage
- Battery charge level dropping quicker than normal
- Problems with regenerative braking
- Activation of additional diagnostic trouble codes (DTCs) like P0A7D – Battery Module Degradation, P0A7A – Hybrid Battery Pack Deterioration, or P0A7F – Battery Energy Control Module Requested MIL Illumination.
How to Fix P0A80 Code?
Replace individual cells
If best one or some cells or modules are faulty, you’ll be able to replace them in preference to the entire battery.
Recondition the battery
If the battery is pretty new, it may be possible to recondition it instead of replacing it. This entails discharging the battery beneath the everyday working stage.
The P0A80 code presentations while the Powertrain control Module (PCM) detects a malfunction within the hybrid vehicle battery management machine or the battery cells.
The trouble code clearly indicates that the car’s battery p.c. has deteriorated and also you want to repair or replace it.
How Much Does it Cost to Fix a P0A80 Code?
Fixing a P0A80 code, which typically indicates a problem with the hybrid battery pack in a hybrid vehicle, can cost anywhere between $2,000 and $8,000.
Depending on the vehicle make and model, the severity of battery damage, and whether individual cells or the entire battery pack needs replacing.
This is because replacing a hybrid battery is often a complex and expensive repair compared to a standard car battery.
