P0A80Replace Hybrid/EV Battery Pack
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
