I don't live in California, so I can't help you in the smog case.

My issue involved my HV cells and the electric water pump that cooled the engine. After rebuilding the HV battery my car was continuing to turn off from over overheating.

After driving my 2013 prius around 630 miles my permanent errors went away.

I rebuilt my HV battery twice more after that. I eventually bought all new cells from Toyota ($2700) because I got tired of rebuilding it. The car is running great now.

I would make sure all the torques on the each cell terminal held 48 inch pounds. Make sure the two orange wires are also cleaned and tight. The P0A80 error could also mean the cells are not balanced evenly. I let my cells sit for a while. 3 days will tell you if they a really bad. Any cell that drops below 7.0 volts in 3 days should be replaced. To balance measure the voltage on each cell. Write that voltage on each cell. Line then up from highest voltage to lowest. Take one cell from each end of the stack (pair the highest with the lowest). Resemble the cells with clean nickel connectors.

I know this video is long and is for a gen2 prius but skip to the part about the cell reconfiguration.

Hope this helps.

Thanks for the info for sure will take note if it if this doesnt resolve but was hoping to hear from the OP whom I quoted and lives in CA claiming his car passed smog with this same permanent code because he had the 15/200 completed.

OK, so you are looking for mrtoofay to respond. Can't you just message him. I was the person who started this thread. About the P0A80.
