What P0A80 means
The battery controller has concluded that the pack is at end of life. In GM tables this is a resistance test: the maximum cell or pack resistance, measured from current and voltage swings, exceeds a temperature-dependent end-of-life threshold, and the code sets as Type A after one trip. Toyota bulletins for Prius (2004–09, 2013–15), Prius v and Camry Hybrid report P0A80, often together with P0A7F, caused by dust in the battery cooling fan; cleaning the fan comes first. Honda recalled the 2018 Accord Hybrid because software wrongly set this code as a permanent fault after pack replacement. Compared with P0A7F it is the final verdict; assist and economy drop and the MIL stays on.
P0A80 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 10 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0A80
- Check engine and hybrid system warning on
- Noticeably weaker electric assist
- Higher fuel consumption, engine runs more
Common causes of P0A80
- Most likelyCell or module resistance above end-of-life limit
- PossibleClogged battery cooling fan or intake filter (Toyota)
- Less likelyController software misreading a replaced pack (Honda Accord Hybrid 2018)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0A80 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| A | Area: hybrid propulsion. |
| 80 | The exact fault in that area. |
What to do next
- Note P0A80 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0A80
What does P0A80 mean?
P0A80 means "Replace Hybrid/EV Battery Pack". The battery controller has concluded that the pack is at end of life. It is a generic code, so it means the same on every make.
Is it safe to drive with P0A80?
Drive gently and only to a workshop. With P0A80 the car can go into limp mode (reduced power) to protect itself.
Will P0A80 fail an emissions test?
Yes, it can. P0A80 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0A80 to fix?
Difficulty: workshop only. A typical repair takes 1 to 10 hours of work. This is a job for a workshop.
Will P0A80 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
